How to Uninstall NodeJS in Ubuntu: Step-by-Step Guide
Step 1: Check if NodeJS is Installed
The first thing you should do is check whether NodeJS is installed on your Ubuntu system. To do this, open a terminal window and enter the following command:
node -v
This will display the version of NodeJS currently installed on your system. If you see a version number, then NodeJS is installed. If not, it means that NodeJS is not installed on your system.
Step 2: Remove NodeJS
Assuming NodeJS is installed on your system, the next step is to remove it. There are several ways to do this, depending on how NodeJS was installed in the first place.
Method 1: Using apt-get
If NodeJS was installed using the apt-get package manager, you can remove it using the following command:
sudo apt-get remove nodejs
Method 2: Using Node Version Manager (NVM)
If NodeJS was installed using NVM, you can remove it using the following command:
nvm uninstall
Replace with the version of NodeJS you want to uninstall. If you want to remove all versions of NodeJS, you can use the following command:
nvm uninstall --all
Method 3: Manual Removal
If NodeJS was installed manually, you'll need to manually remove it as well. This will involve deleting the NodeJS and npm binaries, as well as any associated files and directories.
To do this, first locate the directory where NodeJS is installed. This will typically be /usr/local/bin/, but it could be different depending on how it was installed. Once you've located the directory, run the following commands to remove NodeJS and npm:
sudo rm /usr/local/bin/node
sudo rm /usr/local/bin/npm
You should also remove any other files or directories associated with NodeJS, such as /usr/local/lib/node_modules/.
Step 3: Verify NodeJS is Removed
After removing NodeJS, you should verify that it has been completely removed from your system. To do this, run the node -v command again. If you see an error message indicating that NodeJS is not installed, then you have successfully removed it from your Ubuntu system.
