How to Fix the 'EPERM: operation not permitted' Error with npm on Windows?

"EPERM: operation not permitted" Error on Windows with npm

This error indicates that the user lacks permission to perform a particular operation. In this case, npm commands are being prevented from accessing the directory "C:Program Files (x86)Gitlocal".

The issue is likely caused by an incorrect configuration. The command "npm config set prefix /usr/local" attempted to change the npm prefix to a path that is not valid on Windows. This command should be used only on Unix-based systems.

Solution:

To resolve the issue, reset the npm prefix to a valid path. Open a command prompt as an administrator and run the following command:

npm config edit

This will open the npm configuration file in a text editor. Locate the "prefix" key and change its value to the following:

C:\Users\<user name>\AppData\Roaming\npm</user>

Replace "" with your actual Windows user name.

Save the changes and close the text editor. npm commands should now execute without the "EPERM" error.
