We have discussed how to install NodeJS on Ubuntu systems in our earlier tutorial, but that way we can only use a single installed version of nodejs on our system. What if we want to use another nodejs version, then what should we do ??
We can install NVM on the Ubuntu system. NVM stands for Node Version Manager is used for managing multiple versions of nodejs on a single system by controlling the nodejs versions installed on the system, also it can be used to install nodejs on the system. Basically, it is a command-line utility that allows us to switch between installed multiple nodejs versions.

Currently, it supports Linux & MAC operating systems & doesn’t support Windows but there are some 3rd party tools for Windows that can be used for the same purpose. To install NVM on the Ubuntu system, we can use an install script maintained on GitHub. This will install NVM on Ubuntu as well as CentOS/RHEL/Debian systems as well. So let’s discuss the installation procedure for the same.
Install NVM on Ubuntu
First, we need to download the latest install script for NVM, use the following command to download the latest script from Github,
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
This command will not only download the script but will execute it as well. Once the script finishes, we can either close terminal & open a new session or we can source the ‘~/.bash_profile’ as some new paths for NVM would be added.
$ source ~/.bashrc
Manage NodeJS versions
Once we have nvm installed on our system, we can check the following commands to manage the installed nodejs versions.
1- List all available
To get the list of all available versions that can be installed our system, we will use the following command,
$ nvm list-remote
We will then get list of all the available versions with complete version numbers.
2- Install nodeJs version
To install a nodejs version, we can copy the version number that we got from the above-mentioned command & to install it use,
$ nvm install v0.12.18
We will then install another version also,
$ nvm install v8.1.3
3- List all installed NodeJs versions on the system
To get the list of all the nodejs versions installed on our system, we can use the following command,
$ nvm list
4- Set default nodejs version
To set a default nodejs version for the system, execute the following command,
$ nvm alias v8.1.3
5- Switch to different NodeJs version
To switch to another installed nodejs version, the command is
$ nvm use v0.12.18
6- Uninstall an installed NodeJS version
To uninstall an installed nodejs version, execute the following command,
$ nvm uninstall v8.1.3
