How to Completely Uninstall Node.js and NVM on macOS and Reinstall Them Cleanly?

How to Completely Uninstall Node.js and NVM and Reinstall from Scratch (Mac OS X)

Problem:

Despite installing Node.js and NVM (Node Version Manager), the Node.js version remains stuck at v0.6.1-pre, even after updating it.

Background:

• NVM requires a PATH modification in $HOME/.bashrc.

• On Mac OS X, Node.js and related files are typically stored in the following locations:

  • /usr/local/bin
  • /usr/local/include
  • /usr/local/lib
• NVM may also create a local folder in the user's home directory containing Node.js and npm files.

Solution:

1. Uninstall Node.js:

   • Manually delete the following files and directories:

     • /usr/local/bin/node
     • /usr/local/include/node
     • /usr/local/lib/node_modules (if present)
     • /usr/local/lib/dtrace/node.d (if present)

   • Run the following command:

     brew uninstall node

     Copy after login

2. Uninstall NVM:

   • Open $HOME/.bash_profile or $HOME/.bashrc and remove any references to NVM.

3. Delete Local Folders:

   • Check your home directory for folders named "local", "lib", or "include" and delete any "node" or "node_modules" directories within them.

4. Reinstall Node.js and NVM:

   • Download and install Node Version Manager (NVM).
   • Use NVM to install the desired version of Node.js.

   • If necessary, reinstall npm using:

     npm install -g npm

     Copy after login

5. Additional Steps (Optional):

   • Run the following command to remove any remaining Node.js or npm files:

     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

     Copy after login

By following these steps, you can completely uninstall Node.js, NVM, and related files, and reinstall the entire system from scratch.
