How to Uninstall Node.js and npm on Ubuntu

Node.js is a popular runtime environment that allows developers to run JavaScript on the server side. Paired with npm, the Node.js package manager, it provides a robust environment for developing and deploying web applications.

However, there may be instances where you need to uninstall Node.js and npm from your Ubuntu system, perhaps to reinstall a different version or to free up system resources.

In this guide, we’ll walk you through the steps to completely remove Node.js and npm from your Ubuntu machine.

Let’s get started.

Step 1: Determine Your Installation Method

Before uninstalling Node.js and npm, it’s essential to determine how you initially installed them. The uninstallation process will vary depending on whether you used the Ubuntu package manager, a version manager like nvm, or a manual installation from the Node.js website.

Step 2: Uninstalling Node.js and npm using APT

If you installed Node.js and npm using the Ubuntu package manager (apt), follow these steps:

Next, remove npm with:

To ensure all associated packages and configurations are removed, you can also run:

sudo apt autoremove

Step 3: Uninstalling Node.js and npm using NVM

If you used nvm (Node Version Manager) for installation:

Open your terminal.

List the installed Node.js versions with:

nvm ls

Uninstall a specific version (replace version_number with your version):

nvm uninstall version_number

If you wish to uninstall nvm itself, you can delete it using:

rm -rf ~/.nvm

Step 4: Manual Uninstallation

If you installed Node.js and npm manually from the Node.js website or another source:

Navigate to the installation directory (commonly /usr/local).

Remove Node.js and npm directories:

sudo rm -rf /usr/local/lib/nodejs

Step 5: Verify Uninstallation

After uninstalling, it’s a good practice to verify that Node.js and npm have been removed:
