I have managed to corrupt my npm install, and whenever I try to install packages using npm install, I receive error messages along these lines:
Unhandled rejection Error: EACCES: permission denied, open '/Users/marknorgate/.npm/_cacache/tmp/a449402d'
I have tried reinstalling node & npm, and I have also tried to relocate my npm cache elsewhere using these instructions but nothing works.
How can I get it working?
Restore ownership of the user's npm related folders, to the current user, like this:
sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config
sudo chown -R $(whoami) ~/.npm
sudo chown -R $(whoami) ~/.config
This happens if the first time you run NPM it's with sudo, for example when trying to do an npm install -g.
The cache folders need to be owned by the current user, not root.
sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config
This will give ownership to the above folders when running with normal user permissions (not as sudo).
It's also worth noting that you shouldn't be installing global packages using SUDO. If you do run into issues with permissions, it's worth changing your global directory. The docs recommend:
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
Then updating your PATH in wherever you define that (~/.profile etc.)
export PATH=~/.npm-global/bin:$PATH
You'll then need to make sure the PATH env variable is set (restarting terminal or using the source command)
https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
sudo npm cache clean --force --unsafe-perm
and then npm i goes normally
Above answer didn't work for me. Just try to run your command with --unsafe-perm.
e.g
npm install -g node#latest --unsafe-perm
This seems to solve the problem.
If none of suggestions in answers worked out, try the following command: npm cache clear --force. It worked for me.
I found it at https://github.com/vuejs/vue-cli/issues/1809.
change ownership
sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config
worked for as i installed package using sudo
just create folders _cache/tmp under .npm manually at location /Users/marknorgate/.npm/_cacache/tmp and run your command with administrator access
sudo npm install --unsafe-perm=true --allow-root
This was the one that worked for me
Simply do sudo npm cache clean --force --unsafe-perm and npm i will go normally.
This worked for me!
Resolving EACCES permissions errors when installing packages globally
Try using this:
On the command line, in your home directory, create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
source ~/.profile
Now use npm install it should work.
you can try following command for expo :
sudo chown -R $USER:$GROUP ~/.expo
as per npm community
sudo npm cache clean --force --unsafe-perm
and then npm install goes normally.
source: npm community-unhandled-rejection-error-eacces-permission-denied
Simply run on terminal : sudo chown -R $(whoami) ~/.npm
This worked for me !!
This one works for me:
sudo chown -R $(whoami) ~/.npm
I did not use the -g because I am the only user. I used a MacBook Air.
sudo npm install -g #angular/cli
use this. it worked for me
I just installed node and npm through the package on nodejs.org, and whenever I try to search or install something with npm, it throws the following error unless I sudo the command. I have a feeling this is a permissions issue? I am already the admin.

This looks like a permissions issue in your home directory. To reclaim ownership of the .npm directory execute:
sudo chown -R $(whoami) ~/.npm
Permissions you used when installing Node will be required when doing things like writing in your npm directory (npm link, npm install -g, etc.).
You probably ran Node.js installation with root permissions, that's why the global package installation is asking you to be root.
Solution 1: NVM
Don't hack with permissions, install Node.js the right way.
On a development machine, you should not install and run Node.js with root permissions, otherwise things like npm link, npm install -g will need the same permissions.
NVM (Node Version Manager) allows you to install Node.js without root permissions and also allows you to install many versions of Node to play easily with them.. Perfect for development.
Uninstall Node (root permission will probably be required). This might help you.
Then install NVM following instructions on this page.
Install Node via NVM: nvm install node
Now npm link, npm install -g will no longer require you to be root.
Edit: See also https://docs.npmjs.com/getting-started/fixing-npm-permissions
Solution 2: Install packages globally for a given user
Don't hack with permissions, install npm packages globally the right way.
If you are on OSX or Linux, you can create a user dedicated directory for your global package and setup npm and node to know how to find globally installed packages.
Check out this great article for step by step instructions on installing npm modules globally without sudo.
See also: npm's documentation on Fixing npm permissions.
Also you will need the write permission in node_modules directory:
sudo chown -R $USER /usr/local/lib/node_modules
Changing the owner on "system-global" folders is a hack. On a fresh install, I would configure NPM to use an already writable location for "user-global" programs:
npm config set prefix "${HOME}/npm"
Then make sure you add that folder to your path:
export PATH="${PATH}:${HOME}/npm/bin"
To avoid future issues, do not use sudo npm ... at all.
See #ErikAndreas' answer to NPM modules won't install globally without sudo, and longer step-by-step guide by #sindresorhus with also sets $MANPATH.
Watch OUT!!! Watch OUT!!! Watch OUT!!!
chown or chmod is NOT the solution, because of security-risk.
Instead do this, do:
First check, where npm point to, if you call:
npm config get prefix
If /usr is returned, you can do the following:
mkdir ~/.npm-global
export NPM_CONFIG_PREFIX=~/.npm-global
export PATH=$PATH:~/.npm-global/bin
This create a npm-Directory in your Home-Directory and point npm to it.
To got this changes permanent, you have to add the export-command to your .bashrc:
echo -e "export NPM_CONFIG_PREFIX=~/.npm-global\nexport PATH=\$PATH:~/.npm-global/bin" >> ~/.bashrc
I encountered this when installing Recess (https://github.com/twitter/recess) to compile my CSS for Bootstrap 3.
When installing recess:
-npm install recess -g
You need to unlock permissions in your home directory, like Noah
says:
sudo chown -R `whoami` ~/.npm
You also need write permissions to the node_modules directory, like Xilo
says, so if it still isn't working, try:
sudo chown -R `whoami` /usr/local/lib/node_modules
If you are still seeing errors, you may also need to correct /usr/local permissions:
sudo chown -R `whoami` /usr/local
Please note that as indicated in this post /usr/local/ isn't actually a system dir if you are on a Mac, so, this answer is actually perfectly "safe" for Mac users. However, if you are on Linux, see Christopher Will's answer below for a multi-user friendly, system dir safe (but more complex) solution.
Other answers are suggesting to change ownerships or permissions of system directories to a specific user. I highly disadvise from doing so, this can become very awkward and might mess up the entire system!
Here is a more generic and safer approach that supports multi-user as well.
Create a new group for node-users and add the required users to this group. Then set the ownership of node-dependant files/directories to this group.
# Create new group
sudo groupadd nodegrp
# Add user to group (logname is a variable and gets replaced by the currently logged in user)
sudo usermod -a -G nodegrp `logname`
# Instant access to group without re-login
newgrp nodegrp
# Check group - nodegrp should be listed as well now
groups
# Change group of node_modules, node, npm to new group
sudo chgrp -R nodegrp /usr/lib/node_modules/
sudo chgrp nodegrp /usr/bin/node
sudo chgrp nodegrp /usr/bin/npm
# (You may want to change a couple of more files (like grunt etc) in your /usr/bin/ directory.)
Now you can easily install your modules as user
npm install -g generator-angular
Some modules (grunt, bower, yo etc.) will still need to be installed as root. This is because they create symlinks in /user/bin/.
Edit
3 years later I'd recommend to use Node Version Manager. It safes you a lot of time and trouble.
The official documentation on how to fix npm install permissions with an EACCES error is located at https://docs.npmjs.com/getting-started/fixing-npm-permissions.
I encountered this problem after a fresh install of node using the .pkg installer on OSX. There are some great answers here, but I didn't see a link to npmjs.com yet.
Option 1: Change the permission to npm's default directory
Find the path to npm's directory:
npm config get prefix
For many systems, this will be /usr/local.
WARNING: If the displayed path is just /usr, switch to Option 2.
Change the owner of npm's directories to the name of the current user (your username!):
sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
This changes the permissions of the sub-folders used by npm and some other tools (lib/node_modules, bin, and share).
Option 2: Change npm's default directory to another directory
There are times when you do not want to change ownership of the default directory that npm uses (i.e. /usr) as this could cause some problems, for example if you are sharing the system with other users.
Instead, you can configure npm to use a different directory altogether. In our case, this will be a hidden directory in our home folder.
Make a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
Open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
Back on the command line, update your system variables:
source ~/.profile
I ran into this issue, and while it's true that ~/.npm should be owned by your user, npm was not installing the modules there.
What actually solved my issue is these commands:
npm config set prefix ~/.npm
export PATH="$PATH:$HOME/.npm/bin"
It will make sure that all your global installation will go under this prefix. And it's important that your user owns this directory.
As if we need more answers here, but anyway..
Sindre Sorus has a guide Install npm packages globally without sudo on OS X and Linux outlining how to cleanly install without messing with permissions:
Here is a way to install packages globally for a given user.
Create a directory for your global packages
mkdir "${HOME}/.npm-packages"
Reference this directory for future usage in your .bashrc/.zshrc:
NPM_PACKAGES="${HOME}/.npm-packages"
Indicate to npm where to store your globally installed package. In your $HOME/.npmrc file add:
prefix=${HOME}/.npm-packages
Ensure node will find them. Add the following to your .bashrc/.zshrc:
NODE_PATH="$NPM_PACKAGES/lib/node_modules:$NODE_PATH"
Ensure you'll find installed binaries and man pages. Add the following to your .bashrc/.zshrc:
PATH="$NPM_PACKAGES/bin:$PATH"
# Unset manpath so we can inherit from /etc/manpath via the `manpath`
# command
unset MANPATH # delete if you already modified MANPATH elsewhere in your config
MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
Check out npm-g_nosudo for doing the above steps automagically
Checkout the source of this guide for the latest updates.
TL;DR
always use sudo -i or sudo -H when running npm install to install global packages.
When you use npm, it downloads packages to your user home directory. When you run as sudo, npm installs files to the same directory, but now they are owned by root.
So this is what happens to absolutely every single person who has ever used npm:
install some local packages without issue using npm install foo
install global package using sudo install -g foo-cli without issue
attempt to install local package with npm install bar
get frustrated at the npm designers now that you have to go chmod a directory again
When you use the -i or -H option with sudo, your home directory will be root's home directory. Any global installs will cache packages to /root/.npm instead of root-owned files at /home/me/.npm.
Just always use sudo -i or sudo -H when running npm install to install global packages and your npm permissions problems will melt away.
For good.

q.v. the accepted answer for fixing an already messed up npm.
When you run npm install -g somepackage, you may get an EACCES error asking you to run the command again as root/Administrator. It's a permissions issue.
It's easy to fix, open your terminal (Applications > Utilities > Terminal)
sudo chown -R $USER /usr/local/lib/node_modules
** I strongly recommend you to not use the package management with sudo (sudo npm -g install something), because you can get some issues later **
Reference: http://foohack.com/2010/08/intro-to-npm/
I had a similar problem at NPM modules won't install globally without sudo, the issue was that when i installed node i did it with sudo via chris/lea ppa repo.
My solution was to uninstall node and then install it this way:
Download latest stable node sources from nodejs.org #in my case node-v0.10.20.tar.gz
tar -zxf node-v0.10.20.tar.gz #uncompress sources
cd node-v0.10.20 #enter uncompressed folder
sudo chown $USER -R /usr/local
./configure --prefix=/usr/local && make && make install
PD: If you don't want to change ownership of the /usr/local folder, you can install it somewhere you already own. The problem of this approach is that you will have to bind the installation folder with the bash command line so that we can use the node command later on
mkdir ~/opt
./configure --prefix=~/opt && make && make install
echo 'export PATH=~/opt/bin:${PATH}' >> ~/.bashrc #or ~/.profile or ~/.bash_profile or ~/.zshenv depending on the current Operative System
With either of those approaches, you will be able to do the following without using sudo
npm install -g module_to_install
For me, execute only
sudo chown -R $(whoami) ~/.npm
doesn't work. Then, I execute too
sudo chown -R $(whoami) /usr/lib/node_modules/
sudo chown -R $(whoami) /usr/bin/node
sudo chown -R $(whoami) /usr/bin/npm
And all works fine!
ISSUE: You (the user) don't have the right set of permissions for the directory.
The instant way out is to run the npm install using sudo, but this may give you the same error, or improper installation.
AND changing directory ownership is not a good option, a temporary patch.
Solution/Suggestion: Change npm's Default Directory (from official docs)
Back-up your computer before moving forward.
(optional) In case you have a erroneous installation, first uninstall it:
npm uninstall <package-name> # use sudo if you used it while installation
npm cache verify # or, npm cache clean for npm version below 5.x.x
Make a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
Open or create a ~/.profile or ~/.bash_profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
Back on the command line, update your system variables, or restart the terminal:
source ~/.profile
(optional) Test: Download a package globally without using sudo.
npm install -g jshint
For Mac (adopted from Christoper Will's answer)
Mac OS X 10.9.4
System Preference > Users & Groups > (unlock) > press + :
New Account > "Group"
Account Name : nodegrp
After creating the group, tick the user to be included in this group
sudo chgrp -R nodegrp /usr/local/lib/node_modules/
sudo chgrp nodegrp /usr/bin/node
sudo chgrp nodegrp /usr/bin/npm
sudo chown -R $(whoami):nodegrp ~/.npm
In my case,it's because of the permission of ~/tmp.So I do:
sudo chown -R $USER ~/tmp
And it's OK!
Best solution would be this which is provided by npm documentation.
For Ubuntu suggested solution is Option#2
Brief steps:
Make a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
npm config get prefix can help you to verify if prefix was updated or not. The result would be <Your Home Directory>/.npm-global
Open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
Back on the command line, update your system variables:
source ~/.profile
Instead of steps 2-4 you can also use the corresponding ENV variable
(e.g. if you don't want to modify ~/.profile):
NPM_CONFIG_PREFIX=~/.npm-global
For Mac suggested solution is Option#3
On Mac OS you can avoid this problem altogether by using the Homebrew package manager
brew install node
Problem:
You do not have permission to write to the directories that npm uses to store global packages and commands.
Solution:
Allow permission for npm.
Open a terminal:
command + spacebar then type 'terminal'
Enter this command:
sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
Note: this will require your password.
This solution allows permission to ONLY the directories needed, keeping the other directories nice and safe.
simply try
npm rebuild
then after completion run your usual command
Another great fix here to configure NPM properly, run the following commands :
npm config set prefix '~/.npm_packages'
PATH=$PATH:$HOME/.npm_packages/bin; export PATH
In case sudo chown -R $(whoami) ~/.npm didn't work for you, or you need a non terminal command solution.
The issue is that your user account does not have write permission to node_modules folder, so you can do the following
Open finder and press cmd + shift + g this will open go to folder with url
Write the following path /usr/local/lib/node_modules and press go
Right click on node_modules folder and choose Get Info
Scroll down to sharing & permissions section
Unlock to be able to make changes.
Press + and add your user account
Make sure that you choose Read & Write in privilege drop down
Now you should be able to install packages without sudo and permission issues should be solved
Nobody mentioned this, but there is actually no need to mess up with permissions or a separate npm installation, just specifying a different cache folder to the command will fix the issue
npm install --cache .npm
npm run build --cache .npm
This will create a local .npm folder
What to me seems like the best option is the one suggested in the npm documentation, which is to first check where global node_modules are installed by default by running npm config get prefix. If you get, like I do on Trusty, /usr, you might want to change it to a folder that you can safely own without messing things up the way I did.
To do that, choose or create a new folder in your system. You may want to have it in your home directory or, like me, under /usr/local for consistency because I'm also a Mac user (I prefer not to need to look into different places depending on the machine I happen to be in front of). Another good reason to do that is the fact that the /usr/local folder is probably already in your PATH (unless you like to mess around with your PATH) but chances are your newly-created folder isn't and you'd need to add it to the PATH yourself on your .bash-profile or .bashrc file.
Long story short, I changed the default location of the global modules with npm config set prefix '/usr/local', created the folder /usr/local/lib/node_modules (it will be used by npm) and changed permissions for the folders used by npm with the command:
sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
Now you can globally install any module safely. Hope this helps!
This is how I solved the issue on Windows 8.1:
Go to your nodejs install (usually C:\Program Files\nodejs)
Right click node_modules folder and go to properties
Click the Security tab and advanced
At the top you will see "Owner: SYSTEM", click change
Enter the user you want permissions for and click Ok
Check the box at the bottom of the advanced settings "Replace all child object permission entries with inheritable permission entries from this object" and click ok
Do whatever npm install/update you need
you could try this, works on ubuntu and mac
sudo chown -R $(whoami) /usr/local/lib/node_modules
When trying to install packages globally as root, the process will fail with EUIDLOOKUP or EACCES or npm will mess up your user global packages permissions.
To understand the problem I would suggest reading this issue. In short npm tries to use the EUID of current process to run installation scripts not as root but as the original user running npm while at the same time assuming that a user running as root would use sudo so EUID will be set.
That's why answer of #JHM16 based on using sudo should work.
But this is not the case when installing packages inside a container build. In containers sudo will be more often than not missing. And build will usually just run as root.
Of course container build can be changed to run these commands as a regular user and build everything as that user. This will not make the build more secure though and could be undesirable in some situations.
So in a container build, here's how you can make npm global install work for example with the yarn package.
# setpriv --ruid 0 --euid 0 npm --unsafe-perm install -g yarn
setpriv is a small low level utility that should be available or easily installable on any linux distro.
Actually, I was also having the same problem. I was running Ubuntu. Mine problem arises because I'd lost my public key of the Ubuntu. Even updating my system was not happening. It was giving GPG error. In that case, you can regain your key by using this command:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <key in GPG error>
After that npm works fine!
John Papa points to the history and reasoning behind this issue and gives a solid fix:
John Papa's steps are to:
Use brew to install node without npm
Update your .bash_profile/.bashrc to let npm and node know where to install and find packages
Use brew to update node and npm to update itself
Hope this helps the curious!
#Yves M.'s answer was very similar to my solution. Here are the commands I used, which were slightly different from his.
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh | bash
Then query for the latest version:
nvm ls-remote
Then install the newest version:
nvm install YOUR_VERSION_HERE
example
nvm install v5.8.0
Some of my node modules get installed but there are always these sort of issues on this particular linux mint machine
npm install
npm ERR! Error: EACCES, open '/home/me/.npm/semver/3.0.1/package/package.json'
npm ERR! { [Error: EACCES, open '/home/me/.npm/semver/3.0.1/package/package.json']

This code fix it for me.
sudo chown -R `whoami` ~/.npm
sudo chown -R `whoami` /usr/local/lib/node_modules
UPDATE. See
this answer
for a better way.
You have to set correct permissions (ownership) so npm can access your (sub)directories with your normal user permissions:
sudo chown -R $USER <directory>
where in your case <directory> is /home/me and -R is for recursive to also change ownership of all your subdirectories, which is exactly what you want. That should fix the EACCESS issue.
Sadly the advise to run the command as root/Administrator is wrong here.
You want to avoid running npm with sudo ever, as recommended by the npm creator Isaac Schlueter:
I strongly encourage you not to do package management with sudo! Packages can run arbitrary scripts, which makes sudoing a package manager command as safe as a chainsaw haircut. Sure, it’s fast and definitely going to cut through any obstacles, but you might actually want that obstacle to stay there.
See here for more details.
Add sudo before npm install . It will permit access to write .
sudo npm install [name of package].
Try to use "sudo npx create-react-app app-name"
it may still show error because some dependencies may be mising but a directory and the necessary files maybe created.
Set the correct permission to access the necessary directories.
In my case (Node & NPM Installation via Brew) on BigSur:
sudo chown -R $USER /Users/YOUR_USERNAME/node_modules
If you are still facing problem after running :
sudo chown -R `whoami` ~/.npm
sudo chown -R `whoami` /usr/local/lib/node_modules
Run the npm install command with :
--unsafe-perm
which will help you in installing the package with out any problem.
To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, you will create and use hidden directory in your home directory.
Back up your computer.
On the command line, in your home directory, create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
source ~/.profile
To test your new configuration, install a package globally without using sudo:
npm install -g jshint
(ref: https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally)
Running the code in sudo mode have fixed the problem for me
$ sudo npm install -g nativefier
And if you have related issues like package unmet dependencies check out this link
in windows run cmd as administrator and then try:
npm install -g <package-name>
in mac os or linux try:
sudo npm install -g <package-name>
I understand one might be suspicious about changing the ownership of folders situated in the system files. But it's completely safe, they are meant to host processes that you can use without sudo. So I prefer this solution because it's good and will guarantee compatibility after.
sudo chown -R $USER /usr/local/bin
sudo chmod -R 0775 /usr/local/bin
sudo chown -R $USER /usr/local/lib/node_modules
sudo chmod -R 0775 /usr/local/lib/node_modules
If you installed a new version of node.js, you could still get some error. Try deleting the npm cache:
sudo npm cache clear
To permanently fix this problem, please run:
sudo chown -R 1000:1000 "/home/$USER/.npm"
sudo npm install -g create-react-app
just adding sudo before nmp install will give superuser privilages to run npm and that would not cause any erros while it want to alter a file or access it. well, i hope this might help you!
I had the Similar Problem when I typed:
npm install -g create-react-app
The Terminal replied:
npm ERR! code EACCES
....
So I add "sudo" like This:
sudo npm install -g create-react-app
And problem Solved!! :-)
(So I am agree with "chethan chandan" about using "sudo")
