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'] {

17255 error The operation was rejected by your operating system.

  • The 'Libraries' directory doesn't exists, indeed. But this error also happen on directory that exists, like 'RnTester-js-Tester App.ios', but file inside doesn't. – Thomsath Jun 21 '19 at 09:28

  • cleaning the build folder and rebuilding helped me – Saahithyan Vigneswaran Jun 16 '23 at 06:14

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.

  • There isn't another instance of node that is running on my computer. I restarted it, and nothing change... – Thomsath Jun 21 '19 at 09:28

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

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

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

    It might be a bit confusing to require the VSCode terminal. As far as I can see, every terminal that is run as an administrator would do fine. – shaedrich Mar 25 '21 at 10:28

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>
