How to Fix "EPERM: operation not permitted" Error When Using npm on Windows?

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

When attempting to execute npm commands in a Windows environment, users may encounter the following error:

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

This issue arises after running the following command:

npm config set prefix /usr/local

The problem lies in setting the prefix path to /usr/local, which is not valid for Windows. This action modifies the prefix variable in the directory C:Program Files (x86)Gitlocal.

To resolve this issue, follow these steps:

1. Run the command prompt as an administrator.
2. Execute the command npm config edit to open the configuration file in Notepad.
3. Locate the prefix variable and change its value to C:UsersAppDataRoamingnpm.

Once these changes are made, you should be able to execute npm commands successfully in a regular console.
