How to Completely Uninstall and Reinstall Node.js and Related Tools on macOS

Background:

You are experiencing difficulties updating your Node.js version and encounter a persistent version mismatch between the command line and the Node Version Manager (NVM), despite installing the desired version. You aim to resolve this issue by completely removing and reinstalling Node.js and associated tools.

Solution:

Step 1: Confirm Additional Local Installation

Inspect your user directory for a "local" or "lib" folder. If present, delete any "node" or "node_modules" directories within.

Step 2: Remove Node.js Specific Directories

• Navigate to "/usr/local/include" and remove any "node" and "node_modules" directories.
• Navigate to "/usr/local/lib" and delete any "node" and "node_modules" directories.

Step 3: Uninstall Node.js via Homebrew (If Previously Installed)

If you installed Node.js using Homebrew, execute the following command in the terminal:

brew uninstall node

Step 4: Remove NVM-Related Files

NVM may have made modifications to the PATH variable in your ".bashrc" file. Locate and revert any changes made to this file.

Step 5: Uninstall NPM

If you installed NPM separately, you can uninstall it by deleting the following directory:

~/.npm

Step 6: Uninstall Node Executable

Navigate to "/usr/local/bin" and delete any "node" executable.

Additional Cleanup (Optional):

To ensure thorough removal, you may consider running the following additional command:

sudo rm -rf /opt/local/bin/node /opt/local/include/node /opt/local/lib/node_modules
sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node.1 /usr/local/lib/dtrace/node.d

Reinstallation:

Once everything has been removed, you can proceed with a clean installation of Node.js and related tools.

• Download and install NVM.
• Use NVM to install the desired version of Node.js.
• Node.js versions later than 0.8.0 come bundled with NPM.
