How To Install NVM on Ubuntu 20.04

NVM is a Node Version Manager tool. Using the NVM utility, you can install multiple node.js versions on a single system. You can also choose a specific Node version for applications. It also provides an option to auto-select the node version using the .nvmrc configuration file.

This tutorial will help you to install NVM on Ubuntu 20.04 Linux system. Also, allow you to install different node versions and other useful examples.

Prerequisites

• You must have a running Ubuntu 20.04 Linux system with shell access.
• Log in with a user account to which you need to install node.js.

Installing NVM on Ubuntu

A shell script is available for the installation of nvm on the Ubuntu 20.04 Linux system. Open a terminal on your system or connect a remote system using SSH. Use the following commands to install curl on your system, then run the nvm installer script.

The nvm installer script creates environment entry to login script of the current user. You can either logout and login again to load the environment or execute the below command to do the same.

Installing Node using NVM

You can install multiple node.js versions using nvm. And use the required version for your application from installed node.js.

Install the latest version of node.js. Here node is the alias for the latest version.

To install a specific version of node:

You can choose any other version to install using the above command. The very first version installed becomes the default. New shells will start with the default version of node (e.g., nvm alias default).

Working with NVM

You can use the following command to list installed versions of node for the current user.

With this command, you can find the available node.js version for the installation.

You can also select a different version for the current session. The selected version will be the currently active version for the current shell only.

To find the default Node version set for the current user, type:

You can run a Node script with the desired version of node.js using the below command:

Conclusion

In this tutorial, you have learned to install nvm on Ubuntu 20.04 LTS (Focal Fossa) Linux system. Also, get the basic understanding of the uses of nvm.

NVM – Install and Manage Multiple Node.js Versions in Linux

Node Version Manager (NVM in short) is a simple bash script to manage multiple active node.js versions on your Linux system. It allows you to install multiple node.js versions, view all versions available for installation and all installed versions on your system.

Nvm also supports running of a specific node.js version and it can show the path to the executable to where it was installed, and much more.

In this article, we will explain how to install Node Version Manager (NVM) to manage multiple active node.js versions on your Linux distribution.

Installing Node Version Manager in Linux

To install or update nvm on your Linux distribution, you can download the auto-install script using curl or wget command line tools as shown.

The above auto-install script clones the nvm repository to

/.nvm in your home directory and adds the required source commands to your shell startup scripts i.e

/.bashrc, depending on the shell program you are using as shown in the following screenshot.

Next, verify if the nvm has been installed on your system using the following command.

It will show output as ‘nvm‘ if the installation was successful.

How to Use Node Version Manager in Linux

Now it is time to learn how to use Node Version Manager in Linux.

To download, compile, and install the latest release of node, run the following command:

Note that in the above command, “node” is an alias for the latest version.

Install Latest Node Version in Linux

To install a specific “node” version, first list the available node versions and then install the version as shown.

Install Specific Node Version in Linux

You can check all installed version with the following command:

List Installed Node Versions in Linux

You can use a node.js version in any new shell as shown:

Use Specific Node Version in Linux

Alternatively, simply run a node version as shown (to exit, press ^C ).

Run Node Version in Linux

Importantly, you can view the path to the executable to where a specific node version was installed as follows:

Get Node Installed Location

Furthermore, to manually set a default node version to be used in any new shell, use the alias “default” as shown.

Set Default Node Version in Linux

Note: You can create a .nvmrc initialization file in your project root directory (or any parent directory) and add a node version number or any other flags or usage options that nvm understands, in it. Then use some of the commands we have just looked at above to operate with the specified version in the file.

For more information, see nvm —help or go to the Node Version Manager Github repository: https://github.com/nvm-sh/nvm.

Installing Node.js via package manager

Note: The packages on this page are maintained and supported by their respective packagers, not the Node.js core team. Please report any issues you encounter to the package maintainer. If it turns out your issue is a bug in Node.js itself, the maintainer will report the issue upstream.

Android

Android support is still experimental in Node.js, so precompiled binaries are not yet provided by Node.js developers.

However, there are some third-party solutions. For example, Termux community provides terminal emulator and Linux environment for Android, as well as own package manager and extensive collection of many precompiled applications. This command in Termux app will install the last available Node.js version:

Currently, Termux Node.js binaries are linked against system-icu (depending on libicu package).

Arch Linux

Node.js and npm packages are available in the Community Repository.

CentOS, Fedora and Red Hat Enterprise Linux

Node.js is available as a module called nodejs in CentOS/RHEL 8 and Fedora.

where corresponds to the major version of Node.js. To see a list of available streams:

For example, to install Node.js 12:

For CentOS/RHEL 7 Node.js is available via Software Collections.

Alternatives

These resources provide packages compatible with CentOS, Fedora, and RHEL.

Debian and Ubuntu based Linux distributions

Alternatives

Packages compatible with Debian and Ubuntu based Linux distributions are available via Node.js snaps.

Fast and simple Node.js version manager built in Rust used to manage multiple released Node.js versions. It allows you to perform operations like install, uninstall, switch Node versions automatically based on the current directory, etc. To install fnm, use this install script.
