    Please check the path of node in environment.

    Ensure that the installation directories (C:Program Filesnodejs in your case) have the correct permissions set and that your system PATH includes the path to npm (C:Program Filesnodejs).

    please use npm install -g npm@latest if you are using outdated version.

    1. Update Environment Variables:

    The error message mentions "Could not determine Node.js install directory." This could mean your system environment variables aren’t set correctly. Here’s how to fix it:

    Search for "environment variables" in your Windows search bar.
    Edit your system environment variables (not user variables).
    Find the variable named "Path" and edit it.
    Make sure the path to your Node.js installation directory (e.g., "C:Program Filesnodejs") is included in the list of paths, separated by semicolons (;).
    Save the changes and restart your terminal for the update to take effect.

    Or

    2- Reinstall Node.js
