To confirm the removal, type `node -v` in the Terminal. If uninstalled, you should see a message indicating that ‘node’ is not found.

Uninstalling Node.js on Linux

For Linux users, the method of uninstallation may vary depending on how Node.js was installed. Here are common methods:

Using a package manager: If Node.js was installed via a package manager like apt or yum, you can remove it with:

  • For Debian-based systems:

“`bash
sudo apt-get remove nodejs
“`

  • For Red Hat-based systems:

“`bash
sudo yum remove nodejs
“`

Manual installation removal: If Node.js was installed from source or a binary, you can manually delete it:

  1. Remove the Node.js binary and libraries:

“`bash
sudo rm -rf /usr/local/bin/node
sudo rm -rf /usr/local/lib/node_modules
“`

  1. Check for additional files in other common directories:
  • `/usr/local/include/node`
  • `/usr/local/share/man/man1/node.1`

To verify uninstallation, run `node -v` in the terminal.
