How to Uninstall and Reinstall Node.js, npm, and NVM on Mac OS X

A user recently experienced a persistent outdated version of Node.js (v0.6.1-pre) despite installing newer versions. The investigation revealed a phantom node 0.6.1-pre version that persisted despite various uninstallation attempts.

Solution

The user identified a previously overlooked local folder under the user directory, which contained folders for include, lib, node, and node_modules. Deleting these local references resolved the issue.

Complete Uninstallation and Reinstallation

To completely uninstall Node.js, npm, and NVM and reinstall from scratch:

1. Remove Node.js

• Go to usr/local/lib and delete any node and node_modules folders.
• Go to usr/local/include and delete any node and node_modules folders.
• If installed via brew, run brew uninstall node in the terminal.
• Check the Home directory for any local, lib, or include folders and delete any node or node_modules folders.
• Go to usr/local/bin and delete any node executable.

2. Additional Removal

Consider running the following commands as well:

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

3. Remove NVM

NVM modifies the PATH variable in $HOME/.bashrc; revert this manually.

4. Reinstallation

• Download and install NVM.
• Follow the instructions to install the desired Node.js version.
• Reinstall npm if necessary.
