Install nvm with nodejs

Nodejs is a very popular JavaScript runtime that builds a fast, scalable application running environment from JavaScript scripts. The installation of Nodejs is very simple, but if you need to manage multiple Nodejs versions, you need to use nvm (Nodejs Version Manager) to easily manage different versions of Nodejs on the same computer. This article will introduce how to install nvm using nodejs.

Step One - Install Nodejs

Before installing nvm, you need to install Nodejs. Nodejs provides two installation methods - binary package or source code installation. Binary packages are available for most Unix systems, while source code is available for various Linux distributions, including Ubuntu, Mint, Fedora, Debian, and more.

To install the latest Nodejs version, please visit the Nodejs official website. You can download the binary package or source code and follow the instructions to install it. Note that no additional configuration settings are required.

Step 2 - Install nvm

nvm is a simple and easy-to-use set of commands for managing and installing different versions of Nodejs. nvm allows you to install multiple Nodejs versions on the same computer. You can use nvm to install an earlier or newer Nodejs version, or to switch Nodejs versions between different projects.

To install nvm, please open the terminal and use the following command to download and install the nvm script:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

After the installation is complete, you can check whether nvm is successfully installed by using the following command:

nvm --version

If the installation is successful, the version information of nvm will be output as follows:

0.38.0

Step 3 - Install the Nodejs version

Once you have successfully installed nvm, you can use the following Command to install the required Nodejs version:

nvm install [node.js version number]

For example, to install the Nodejs 14.17.3 version, use the following command:

nvm install 14.17.3

After the installation is complete, you can use the following command to view what is installed Nodejs version:

nvm ls

Output example:

       v14.17.3
        v16.2.0
->      system
default -> 14.17.3 (-> v14.17.3)
node -> stable (-> v16.2.0) (default)
stable -> 16.2 (-> v16.2.0) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/fermium (-> v14.17.3)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.24.1 (-> N/A)
lts/erbium -> v12.22.3 (-> N/A)
lts/fermium -> v14.17.3

In the above example, you can see the list of installed versions, as well as the currently activated default version. The version marked with an arrow is the default version.

Step 4 - Switch Nodejs version

When you need to switch Nodejs versions between different projects, you can use the following command to activate the required version:

nvm use [node.js version number]

For example, to use Nodejs 14.17.3 version, use the following command:

nvm use 14.17.3

After using the above command, you can successfully switch to the desired Nodejs version.
