2. Install NVM
NVM (Node Version Manager) is a bash script used to manage multiple active Node.js versions.
To install NVM, run the following command:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
3. Install the latest version of Node.js
Once NVM is installed, you can install the latest version of Node.js using the following command:
nvm install node
4. Set the default version of Node.js
Once the installation is complete, you can set the default version of Node.js using the following command:

How to Update Node.js to Latest Version Ubuntu Linux
By following these simple steps, you can easily install and switch between different versions of Node.js on your Ubuntu linux system:
- Step 1: Check the Current Node.js Version
- Step 2: Install Node Version Manager (NVM)
- Step 3: Install a New Node.js Version
- Step 4: Switch to the New Node.js Version
- Step 5: Check the Node.js Version Again
Step 1: Check the Current Node.js Version
Before upgrading or updating Node.js, it is important to check the current version running on your Ubuntu system. To do this, open the terminal and type the following command:
node -v
This will display the current version of Node.js installed on your system.
Step 2: Install Node Version Manager (NVM)
Node Version Manager (NVM) is a useful tool for managing and switching between different Node.js versions. If you do not have NVM installed on your system, you can install it using the following command:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
This command will download and install NVM on your Ubuntu system.
Step 3: Install a New Node.js Version
Once you have NVM installed, you can install a new Node.js version using the following command:
nvm install [version number]
Replace [version number] with the desired version of Node.js you want to install. For example, to install Node.js version 16, you can use the following command:
nvm install 16
This command will download and install Node.js version 16 on your Ubuntu system.
Step 4: Switch to the New Node.js Version
After installing a new Node.js version, you can switch to it using the following command:
nvm use [version number]
Replace [version number] with the Node.js version you want to use. For example, to switch to Node.js version 16, you can use the following command:
nvm use 16
This command will set the default Node.js version to version 16.
Step 5: Check the Node.js Version Again
Finally, you can verify that the new Node.js version is installed and active by running the following command:
node -v
This should display the version of Node.js you installed using NVM.
