"EPERM: operation not permitted" on Windows with npm

I ran

npm config set prefix /usr/local

After running that command, When trying to run any npm commands on Windows OS I keep getting the below.

Error: EPERM: operation not permitted, mkdir 'C:\Program Files (x86)\Git\local'
at Error (native)

Have deleted all files from

C:\Users\<your username>\.config\configstore\

It did not work.

Any suggestions?

Solution

  • Running this command was my mistake.

    npm config set prefix /usr/local

    Path /usr/local is not for windows. This command changed the prefix variable at 'C:\Program Files (x86)\Git\local'

    To access and make a change to this directory I need to run my cmd as administrator.

    So I did:

    1. Run cmd as administrator
    2. Run npm config edit (You will get notepad editor)
    3. Change prefix variable to C:\Users\<User Name>\AppData\Roaming\npm

    Then npm start works in a normal console.
