Resolving npm and gulp Command Errors: Operation Not Permitted in Admin Mode

Have you ever run into an annoying situation where your npm and gulp commands only work when you run them as an admin? If these commands fail to execute and yield an error similar to "Operation not permitted," you're not alone. This issue can stem from how your Node.js version manager (nvm) is configured, particularly regarding file permissions in Windows.

In this guide, we’ll guide you through the steps to resolve this frustrating problem and get your development environment back to normal.

The Problem

When users try to run npm or gulp commands from a standard user account, they may receive an error like this:

This message means your system doesn't have the proper permissions to access the required files. You might notice that other commands, like dotnet and node, work without issue, leaving you puzzled.

What Causes This?

The likely culprit is how nvm installs Node.js versions. If nvm is set to install Node.js versions into a location tied to your admin account, which is typically inaccessible when running as a non-admin, that’s where the issue arises.

The Solution

Here's a step-by-step guide to fixing the permission errors associated with your npm and gulp commands.

Step 1: Open CMD as Admin

Search for "Command Prompt" in your Windows search.

Right-click on it and select "Run as administrator".

Step 2: Check Your NVM Root

Type the command below to check the current root directory:

Step 3: Remove Old Node.js Shortcut

Navigate to the C:\Program Files\ directory.

Delete the nodejs shortcut folder pointing to your admin directory.

Step 4: Create a New Directory

In C:\Program Files\, create a new folder named nodev.

Step 5: Set a New Root for NVM

In the command prompt (still running as admin), set your nvm root to the newly created folder:

Step 6: Reinstall Node.js Version

Use nvm to install your desired Node.js version again:

Step 7: Verify Installation

Open a new command prompt (this time without admin privileges).

Check if Node.js and npm are accessible by running:

If everything is set up correctly, you should see version numbers for both commands, confirming they are ready to use in standard user mode.

Conclusion

Resolving issues with npm and gulp commands can initially seem overwhelming, especially when error messages indicate administrative permissions are required. However, by adjusting your nvm root directory and ensuring that installations occur in a non-administrative accessible path, you can solve the problem effectively.

With these steps, you should now have a conducive working environment for your development needs. Enjoy coding without the hassle of permission errors!
