How to Uninstall Node.js on macOS: A Comprehensive Guide

Node.js is a popular runtime environment for JavaScript that powers countless applications and web services. While it's a powerful tool, you might find yourself needing to remove it from your macOS system, whether for troubleshooting, testing a different version, or simply freeing up disk space.

This article will guide you through the process of uninstalling Node.js on macOS, providing clear instructions and addressing common questions.

Methods for Uninstalling Node.js on macOS

There are two primary methods for removing Node.js from your macOS system:

1. Using Homebrew (Recommended):

If you installed Node.js using Homebrew, the most straightforward way to remove it is with the brew command.

How to do it:

1. Open your Terminal: You can find the Terminal application by searching for it in Spotlight.
2. Run the following command:

   brew uninstall node
   

3. Confirm the uninstallation: Homebrew will ask you to confirm the uninstallation. Type 'y' and press Enter to proceed.

2. Manual Uninstallation:

If you didn't use Homebrew or prefer a manual approach, follow these steps:

1. Identify the Installation Directory: Node.js typically installs itself in /usr/local/bin and /usr/local/lib.
2. Remove the Node.js Files: Navigate to these directories using the Terminal and delete the Node.js files and directories:

   sudo rm -rf /usr/local/bin/node
   sudo rm -rf /usr/local/bin/npm
   sudo rm -rf /usr/local/lib/node_modules
   

   Note: Use caution when using sudo, as it allows you to run commands with administrative privileges.
3. Clean up the Environment Variables: Edit your .bash_profile or .zshrc file to remove any references to Node.js paths, including the PATH variable.
4. Verify Removal: After removing the files, check if Node.js and npm are still available by running node -v and npm -v in the Terminal. You should see an error message indicating they are not found.

Addressing Common Questions

Q: What about npm?

A: Uninstalling Node.js also removes npm (Node Package Manager) since it's bundled with Node.js.

Q: Will this remove my Node.js projects?

A: No, uninstalling Node.js will not remove your projects. Your project files and code will remain intact.

Q: How do I check which version of Node.js I have?

A: You can use the following command in your Terminal to check your Node.js version:

node -v

Q: Can I install multiple versions of Node.js?

A: Yes, you can use a Node.js version manager like nvm (Node Version Manager) or n to install and manage multiple Node.js versions on your system.

Conclusion

Uninstalling Node.js from macOS can be done in a few simple steps. Whether you choose the Homebrew method or manual removal, this guide provides the necessary information to successfully remove Node.js from your system.
