Uninstalling Node.js on Windows

To delete Node.js from a Windows system, you can utilize the built-in uninstallation feature. Follow these steps:

  1. Open the **Control Panel**.
  2. Navigate to **Programs** > Programs and Features.
  3. Scroll through the list of installed applications and find Node.js.
  4. Right-click on it and select Uninstall.
  5. Follow the prompts to complete the uninstallation process.

After uninstalling, it’s advisable to check for any remaining files or folders:

  • Navigate to `C:\Program Files\nodejs` and delete the folder if it exists.
  • Additionally, check for any leftover npm packages in your user directory, typically found at `C:\Users\\AppData\Roaming\npm`.

Uninstalling Node.js on macOS

To uninstall Node.js from a macOS system, you can use the terminal. Follow these steps:

  1. Open the Terminal application.
  2. Execute the following commands to remove Node.js and npm:

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

  1. Verify that Node.js has been removed by typing `node -v` and `npm -v`. You should see an error indicating that the commands are not found.

Uninstalling Node.js on Linux

On Linux, the method to uninstall Node.js depends on how it was installed. If you used a package manager like apt or yum, you can remove it using the following commands:

For Debian-based systems (like Ubuntu):

“`bash
sudo apt-get remove nodejs
sudo apt-get purge nodejs
“`

For Red Hat-based systems (like CentOS):

“`bash
sudo yum remove nodejs
“`

If you installed Node.js using nvm (Node Version Manager), you can uninstall it by:

“`bash
nvm uninstall
“`

Replace `` with the specific version number you wish to remove.

Verifying Node.js Removal

After the uninstallation process, it’s essential to verify that Node.js has been completely removed. This can be done by checking the version of Node.js and npm:

Command Expected Output
`node -v` Command not found error
`npm -v` Command not found error

If both commands result in a “command not found” error, it indicates that Node.js has been successfully uninstalled from your system.

Cleaning Up Environment Variables

In some cases, even after uninstalling Node.js, remnants may remain in your environment variables. To clean these up:

  1. Windows:
  • Right-click on This PC or My Computer and select Properties.
  • Click on Advanced system settings.
  • Click on Environment Variables.
  • Check for any entries related to Node.js or npm and remove them.
  1. macOS and Linux:
  • Open your terminal and edit your shell configuration file (like `.bashrc`, `.bash_profile`, or `.zshrc`).
  • Look for lines that export paths related to Node.js or npm and remove them.
  • Save the changes and run `source ~/.bashrc` or the equivalent for your shell.

By following these steps, you ensure a clean removal of Node.js from your system.

Uninstalling Node.js on Windows

To delete Node.js from a Windows system, follow these steps:

  1. Open Control Panel:

  1. Uninstall Node.js:
  • Right-click on “Node.js” and select “Uninstall.” Follow the prompts to complete the uninstallation process.
  1. Remove Remaining Files (if necessary):
  • Check for leftover files in the installation directory, typically found in `C:\Program Files\nodejs`. Delete this folder if it exists.
  1. Update Environment Variables:
  • Right-click on “This PC” or “My Computer,” select “Properties,” and then “Advanced system settings.”
  • Click on “Environment Variables” and remove the Node.js path from the “Path” variable, if present.

Uninstalling Node.js on macOS

To remove Node.js from a macOS system, execute the following steps:

  1. **Open Terminal**:
  • You can find Terminal in `Applications > Utilities` or by searching using Spotlight.
  1. Remove Node.js via Homebrew (if installed with Homebrew):

“`bash
brew uninstall node
“`

  1. Manual Removal (if installed via package installer):
  • Execute the following commands in Terminal:

“`bash
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 Remaining Files:
  • Verify if any files remain in `/usr/local/lib` or `/usr/local/bin` and remove them accordingly.

Uninstalling Node.js on Linux

For Linux distributions, the process may vary slightly based on the package manager used. Below are commands for common package managers:

  • Using APT (Debian/Ubuntu):

“`bash
sudo apt-get remove nodejs
sudo apt-get purge nodejs
“`

  • Using YUM (CentOS/RHEL):

“`bash
sudo yum remove nodejs
“`

  • Using DNF (Fedora):

“`bash
sudo dnf remove nodejs
“`

After removing Node.js, you may want to delete any residual configuration files:

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

Verifying Node.js Removal

To ensure that Node.js has been successfully uninstalled from your system:

  • Check Node.js Version:

Open your command line or terminal and type:
“`bash
node -v
“`
If Node.js is removed, you should see a message indicating that the command is not recognized.

  • Check npm Version:

Similarly, check npm by typing:
“`bash
npm -v
“`
A similar error indicates successful removal.

Reinstalling Node.js

If you plan to reinstall Node.js, consider using the official installer or a version manager like nvm (Node Version Manager) for easier management of multiple Node.js versions.

  • Using nvm:
  1. Install nvm by following the instructions on the [nvm GitHub page](https://github.com/nvm-sh/nvm).
  2. Use nvm to install Node.js:

“`bash
nvm install node
“`

This method allows for easier switching between different Node.js versions, enhancing flexibility for development needs.
