Errors when doing npm install - npm

I've already installed Node.js in my machine. When I try npm install, the installation does not properly work for me. I get the following on my console:
Installed node version 14.15.1
Installed npm version 6.14.8
Installed angular cli version 11.2.3
And then some errors pop up. Here's a screenshot of my console:

Any of the following methods might be useful for you:
Method 1: Clean cache & then perform an installation
npm cache clean --force
npm install
Method 2: Exclude package-lock.json file and perform an installation
npm install --no-package-lock
Method 3: Manually delete node_modules and package-lock.json file and then perform an installation
npm install

prevent npm from removing node_modules folder on failure

I want to npm install a broken package, i.e., the installation process does not work properly and results in an error. I am used to npm keeping the successfully installed packages in the local node_modules folder. For some reason npm has stopped doing that and removes the node_modules folder if the install is not successful.
How can I tell npm to keep the local node_modules folder regardless of the success or failure of the installation process?
I faced a similar problem when one of the packages failed to build its C++ addon and npm removed node_modules. The below steps helped me:
Install the packages with scripts disabled.
$ npm install --ignore-scripts
Fix the package
...
Rebuild the package
$ npm rebuild PACKAGE

npm install result in an incomplete module, but yarn install is successful, why they behave differently?

I tried npm install and npm install --no-optional for my forked repository, and it was not installed completely: git+https://github.com/marsonmao/react-sketch#v0.4.104 (link).
After using npm install, only part of the repository was installed: there are only /node_modules and .eslintrc, karma.config.js, README.md...etc in MyProject/node_modules/react-sketch, but no /lib and /src...etc.
Then I tried yarn install and it was successful, every file in the repository was installed.
So why npm failed however yarn succeeded?
npm version: 5.5.1, yarn version: 1.3.2

npm does not install new package after modifying package.json

I have a web application with some packages defined in package.json after I run npm install all dependencies are resolved. However when I add some packages after that to package.json and run npm install again nothing happens. I did the work around by typing npm install --save lodash and it downloaded the dependency and updated packages.json. It works, but let's imagine the scenario when I want to add 10 or more packages. Then it would be easier for me to just add them to package.json and run npm install but this does not work :/. So what would be the solution for the problem off adding more packages after initial npm install?
Node version: v8.1.3
npm version: 5.03
Operating System: Windows 10 Pro

Error: EPERM: operation not permitted, unlink 'D:\Sources\**\node_modules\fsevents\node_modules\abbrev\package.json'

I just updated npm to 5.4.0.
Now, Whenever I want install a npm package I get the following error:
D:\Sources\DownloadCms\Md.Download\Web.Angular>npm install mds.angular.datetimepicker#latest --save

I'm dead sure, run CMD as administrator.
Also I checked D:\Sources\DownloadCms\Md.Download\Web.Angular\node_modules\fsevents\node_modules\abbrev\package.json\, package.json is not exist in path !
Edit:
Upgrade to v5.4.1, still get the same error, even cannot work around with --no-optional :-(
I was able to fix this by running the command prompt/bash as admin and closing VSCode!
Seems like VSCode was locking some files.
Potentially something else could be locking these files for you.
It is an npm 5.4.0 issue https://github.com/npm/npm/issues/18287
Workarounds are
downgrade to 5.3
try running with --no-optional, i.e. npm install --no-optional
Please close all IDE like visual studio code. run npm install command through node.js command prompt.
Enjoy !
If you downgrade to 5.3 and still get the same error in Windows like me.
After hours working with npm versions I found the following solution:
1. Download latest recommended version of nodejs, these days is node-v6.11.3-x64
2. Uninstall nodejs with it.
3. Go to C:\Users\{YourUsername}\AppData\Roaming folder and delete npm and npm-cache folders
4. Run installer of nodejs again and install it
5 Update npm to 5.3 with npm i -g npm#5.3 command line
Now you should use npm without any issues.
I tried this solution found at a How to fix Node.js blog
just use
npm cache clean
in windows if it refuses use
npm cache clean --force
cache clean and npm update to latest with force work for me
npm cache clean --force
npm install -g npm#latest --force
I fixed by downgrading npm from 5.4.0 to version 5.3
npm i -g npm#5.3
I Hope this helps for you
I had the same problem on Windows.
The source of the problem is simple, it is access permission on folders and files.
In your project folder, you need
After cloning the project, change the properties of the folder and change the permissions of the user (give full access to the current user).
Remove the read-only option from the project folder.
(Steps 1 and 2 take a long time because they are replicated to the entire tree below).
Inside the project folder, reinstall the node (npm install reinstall -g)
Disable Antivirus. (optional)
Disable Firewall. (optional)
Restart PC.
Clear the npm cache (npm clear)
Install the dependencies of your project (npm install)
After that, error "Error: EPERM: operation not permitted, unlink" will no longer be displayed.
Remember to reactivate the firewall and antivirus if necessary.
I had the same issue and all I needed to do was login to npm
npm login
or alternatively
npm add user // consult the documentation for the params
For those who are coming from Windows OS, you just need to stop the development server and then execute your npm install ... command.
It is strange how Windows doesn't allow installing dependencies while server is running, but MacOS does allow.
If this doesn't work, then only go for the other options - clean cache, downgrade nodejs etc.
If all of the above failed to work for you, you might want to
restart your system
run command prompt as admin
run the npm command
In my case, the problem was that, I did not install typescript. Although I did install Node and Angular.
To check if you have installed typescript or not
Run this command: tsc -v
If not, then to install typescript
Run this command: npm install -g typescript
And, finally to install required dependencies
Run this command: npm install
in the root folder of the project.
---- Hope this helps someone ----
I had this logs in Windows.
I did the following
Close Visual Studio Code
Run Command Line as admin
Deleting package-lock.json fixed it for me.
I'm using VsCode and solved this issue by stopping the application server and them run npm install. There are files that were locked by the application server.
No need to close the IDE, just make sure there's no another process locking some files on your projects.
Mine was as a result of opening my project folder a 2 different terminals. I solved it by closing all running terminal (vs code was excluded) and executing the installation command again.
I hope this helps someone.
NB: deleting node_modules didn't solve it.
For me it worked in bash from git package
try:
C:\Program Files\Git\bin\bash.exe
then:
npm install mds.angular.datetimepicker#latest
There seems to be many solutions out there that worked with downgrading npm versions. For me, the solution was
npm install -force
I tried the downgrading of npm versions, modifying my npm prefix config to match the npm directory, and clearing cache. None of these worked, but apparently they worked for others, so it may be worth a shot.
For me on Windows the problem was too long path length. I moved the project to a smaller length path and it worked.
Deleting my node modules folder and running a normal npm install did it for me
For me it was Docker...
The moment that I closed the app container, I could do an npm install without any proble
P.S My node version is 14.15.5
I fixed this by removing the dist folder
--- Remove dist or public folder
the same error comes to me when i update the npm version to the latest 5.4
downgrade to the version 5.3.0 is useful.the error comes from the npm 5.4,you can check it in the issuses in npm 5.4
npm install npm#5.3 -g
Fixed in NPM 5.6.0
Upgrade to NPM 5.6.0 solved problem for me.
I wanted to run npm install from within my external hard drive as this is where i saved my code workspace. Windows 10 OS.
But I was getting the same error as the original post.None of the previous answers worked for me, I tried all of them:
uninstalling nodejs then re-installing
uninstalling nodejs then downgrading/installing a lower version of nodejs.
npm install -force
deleting the folders from C:\Users{YourUsername}\AppData\Roaming ... npm and npm-cache then re-installing.
npm cache clean --force
npm cache clean
npm install --g or npm install --global
What worked for me was this:
copy the folder from C:\Program Files\nodejs to D:\Program Files\nodejs
Then go to Control Panel\System and Security\System
Advanced System Settings
Environment Variables
System Variables
Double click Path
Add a new path
D:\Program Files\nodejs
Click ok
restart PC.
try npm install from within D: Drive
npm cache verify solved my issue.
I was doing: ng new my-app
and I faced similar error
I have
node version: 10.16.0
npm v 6.9.0
After trying everything, including node/npm upgrade, cache cleaning and reverting code, nothing helped besides one simple thing: Turning OFF Windows 10's Real-time protection during the dev/build. Looks like latest updates made it super aggressive.
npm login is required before publish
For windows,
Download latest recommended version of nodejs, these days is node-v6.11.3-x64
Uninstall nodejs with it.
Go to C:\Users\{YourUsername}\AppData\Roaming folder and delete npm and npm-cache folders
Run installer of nodejs again and install it
By default npm 3.10.10 should be installed along with node-v6.11.3-x64.
It worked for me with npm 3.10.10 but did not work with 5.3.X.
Also it did not worked with higher versions of node (above
node-v6.11.3-x64)
My problem was executing the command (npm audit fix all). I solved it when closing VSCODE and re-executed the command without problems.

Installing protractor on offline machine

I have downloaded protractor git repo and tried to install it on my offline machine
using:
npm install <folder-path>
it give me the following error:
npm err! getaddrinfo EAI_AGAIN
I assume it happens because it tries to download all the dependencies from the internet but fails.
Is there a way to install it offline? What files do I need?
npm has a local cache, so if you install it once with npm install protractor, you'll be able to install it offline next time you need it.
Another solution is just to install it once and the copy all the node_modules.
