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

  1. Check for any remaining Node.js files using:

“`bash
which node
which npm
“`

If any paths are returned, you may need to remove those files manually.

Cleaning Up Node.js Environment Variables

After uninstalling Node.js, you may want to clean up any environment variables related to Node.js or npm. Follow these steps:

  1. Open your shell configuration file, commonly `.bash_profile`, `.bashrc`, or `.zshrc`, depending on your shell.
  2. Look for any lines that export Node.js or npm paths. They might look like this:

“`bash
export PATH=$PATH:/usr/local/bin/node
export PATH=$PATH:/usr/local/bin/npm
“`

  1. Remove those lines, save the file, and refresh your terminal session:

“`bash
source ~/.bash_profile or the appropriate file
“`

Verifying the Uninstallation

After completing the uninstallation process, it is crucial to ensure that Node.js has been removed completely. Use the following commands:

  • Check for Node.js:

“`bash
node -v
“`

  • Check for npm:

“`bash
npm -v
“`

Both commands should return an error indicating that the commands are not found.

Using Node Version Manager (NVM)

If you installed Node.js using NVM (Node Version Manager), uninstallation is also quite simple:

  1. To uninstall a specific version of Node.js, use:

“`bash
nvm uninstall
“`

Replace `` with the version number you want to remove (e.g., `14.17.0`).

  1. To list all installed versions of Node.js, run:

“`bash
nvm ls
“`

  1. After uninstalling, verify that the version has been removed by checking the installed versions again.

The process of uninstalling Node.js on macOS can vary depending on how it was initially installed. By following the appropriate steps for Homebrew, the official package installer, or NVM, users can ensure a clean removal of Node.js from their system.

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
