npm ERR! Error: EPERM: operation not permitted, unlink

I'm working on an expo application. I would like to install all the packages on my expo application (npm install). But, an error occured :

17254 error [OperationalError: EPERM: operation not permitted, unlink ... I have seen this error on many subjects, but no one answer to my problem.

I've already tried to :

  1. Launch my terminal as an administrator.
  2. npm config set safe-perm=true.
  3. npm install --no-bin-links
  4. npm cache clear --force

An exemple of error message that I have : 

17254 error   cause: [Error: EPERM: operation not permitted, unlink 'C:\Users\Thomas\Desktop\someDirectory\someDirectory\someDirectory\someDirectory\node_modules\.staging\react-native-99ed309f\Libraries\Renderer\oss\ReactFabric-dev.js'] {
17254 error     errno: -4048,
17254 error     code: 'EPERM',
17254 error     syscall: 'unlink',
17254 error     path: 'C:\\Users\\Thomas\\Desktop\\someDirectory\\someDirectory\\someDirectory\\someDirectory\\node_modules\\.staging\\react-native-99ed309f\\Libraries\\Renderer\\oss\\ReactFabric-dev.js'
17254 error   },
17254 error   stack: 'Error: EPERM: operation not permitted, unlink ' +

17254 error }
17255 error The operation was rejected by your operating system.
17255 error It's possible that the file was already in use (by a text editor or antivirus),

17255 error If you believe this might be a permissions issue, please double-check the

17255 error the command again as root/Administrator (though this is not recommended).
17256 verbose exit [ -4048, true ] ```

Try installing it globally first, using the command

  • npm install -g create-react-app

And then, you can create your app using the command,

  • npx create-react-app <Name_of_your_app>

What I did is:

  1. Deleted node_modules folder;

  2. Opened VSCode as administrator;

  3. Ran the following commands in terminal:

    npm cache clean --force

    npm install

I had this error message, to solve it you have to:

1) add your project folder in Windows Defender exclusions list.

2) remove your node_modules folder

3) run:

npm install

Solved it by logging into npmjs: npm login

or

uninstall all npm modules and re-install with npm install --no-bin-links

or

rd /s /q C:\Users\foo\AppData\Roaming\npm-cache
rd /s /q C:\Users\foo\AppData\Roaming\npm

Is there a another instance of node running, that is also using ReactFabric-dev.js? If so, terminate and retry. Also try to move your project to a folder "closer" to root. Windows sometimes gets confused with very long paths.
