On npm install: Unhandled rejection Error: EACCES: permission denied - npm

Question

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?

Answer 1

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

Answer 2

sudo chown -R $(whoami) ~/.npm
sudo chown -R $(whoami) ~/.config

Answer 3

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)

Answer 4

sudo npm cache clean --force --unsafe-perm
and then npm i goes normally

Answer 5

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.

Answer 6

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.

Answer 7

change ownership
sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config
worked for as i installed package using sudo

Answer 8

just create folders _cache/tmp under .npm manually at location /Users/marknorgate/.npm/_cacache/tmp and run your command with administrator access

Answer 9

sudo npm install --unsafe-perm=true --allow-root
This was the one that worked for me

Answer 10

Simply do sudo npm cache clean --force --unsafe-perm and npm i will go normally.

Answer 11

This worked for me!
Resolving EACCES permissions errors when installing packages globally

Answer 12

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.
