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).

How to Install Node.js from Linux Terminal

Node.js is an open-source, free, cross-platform JavaScript run-time environment which is responsible for executing JavaScript code on server. It allows developers to use JavaScript for server-side scripting — running scripts server-side to produce dynamic web page content before the page is sent to the user’s web browser. Consequently, Node.js represents a «JavaScript everywhere» paradigm, unifying web application development around a single programming language, rather than different languages for server side and client side scripts.

In this tutorial, I will show you how to install the latest Nodejs on Ubuntu 18.04, CentOS 7, and Arch Linux from the terminal.

There are several ways to install Node.js on Linux machine and we are going to cover them in this article.

• Install using Node Version Manager (NVM)
• Install using the Github source code clone
• Install the Distro-Stable version of Node.js

Install using Node Version Manager (NVM)

NVM doesn’t work at the operating system level, instead it works at the level of a directory within your user’s home directory. It allows installing multiple, self-contained versions of Node.js without affecting the entire system.

Ubuntu 18.04

Before installing NVM we update OS with the following command

To use nvm, we must have curl, build-essentials libssl-dev packages installed on the system. To install them type

Once all prerequisites are available we install nvm with the following command

The script above clones the nvm repository to

/.nvm and also adds the source line to your profile (

/.bashrc). That means we need to source the profile file. To do so, type the following command

Now nvm functionalities and binaries are available for use and we can get list of available Node.js versions via the following command

Tail of output must look like the one below:

Choose the version you want to install and type the command below to install it.

After installing the desired version we can set that version as default Node.js version (in case you have multiple installations)

To check if version is installed and set to default successfully, just check Node.js version with the command below

The output of this command must show the installed version.

To update/install another version you can run:

Make sure to run the command with the version you want to install. After you can set the freshly installed version as your default with the following command:

To remove node.js version via nvm, first check if it’s not the current version with the command below

and run the following command to remove the desired version:

CentOS 7

The process of installation of nvm and node.js using nvm is the same as on Ubuntu 18.04 with few differences. Below you can find commands running which in the same order will install nvm, node.js and set the default version.

Source profile file (note that in CentOS it differs from the one in Ubuntu)

List available node.js versions

Install the desired version (make sure to change with the version you want to install)

Set as default node.js version

Check if installation and default setting are succeeded

To update/install another version you can run:

Make sure to run the command with the version you want to install. After you can set the freshly installed version as your default with the following command:

To remove node.js version via nvm, first check if it’s not the current version with the command below

and run the following command to remove desired version:

Install using the Github source code clone

To install Node.js using release from official Github repository we need to check make sure the make , gcc , g++ and python packages are installed on Ubuntu 18.04 machine. If there are missing packages, you can run:

On CentOS 7 all needed packages are preinstalled in OS. You can run OS update command to make sure they are latest versions:

The rest part of installation using GitHub repository’s official release is the same for both distributions.

Download the desired release (e.g. v6.2.1) from Github Repo using the following command:

Extract the content of the archive using the command below

Enter the directory with extracted files

and run the following command to compile

After compilation you can now install node.js using the following command:

The process of installation can take little bit longer this way. It depends on resources of your machine.

Install the Distro-Stable version of Node.js

In default repositories of Linux distributions, there are versions of Node.js and you can install them using any package manager of the distribution (apt for Ubuntu, yum for CentOS and etc. ). The main issue with this type of installation is that the versions available in official repositories may be outdated. For example, at the moment of writing this tutorial the latest version of Node.js in Ubuntu’s repositories is v8.10.0, and in CentOS epel-release repo the latest available version is v6.14.0. But using nvm we can install v10.0.0 at the same time. However, below you can find steps to install latest available stable version of Node.js for each distro.

Ubuntu 18.04

Before installing Node.js on your Ubuntu 18.04 machine, update you OS to the latest version. To do so, you can run:

Now you can install Node.js using the following command:

Also you can install npm (Node.js package manager) to install modules and packages. To install npm , run the command below:

After installation, you can check the version of Node.js (note that the executable from the Ubuntu repositories is called nodejs instead of node )

To update Node.js on Ubuntu 18.04 machine either update OS with the command:

or run install command. It will update the existing version if there are updates:

To remove Node.js from your Ubuntu 18.04 machine run the following command:

CentOS 7

To install Node.js on CentOS 7 machine using official repositories follow the steps below.

First, install epel-release repository on your machine using the following command:

This will allow you to install Node.js. To do so, you can run:

Check the installed version with the command below:

And finally you can install npm (Node.js package manager) using the following command:

To update Node.js on CentOS 7 machine either update OS with the command:

or run install command. It will update the existing version if there are updates:

To remove Node.js from your CentOS7 machine run the following command:

Arch Linux

To install Node.js on Arch Linux, use the following command:

To install npm, you can run:

To remove Node.js from Arch Linux typ:

Check if Node.js is working using script

To check if our installation (doesn’t matter which way) is successful and node.js is working properly, we are going to create very simple «Hello World» app and check if everything works fine. To do so, we create hello-world.js in our home directory file using the command below:

and add the following content into it and save the file:

Now we run the app with the following command

The output must be the one shown below

That means that node.js is installed correctly and working properly. You can now go ahead and create your incredible apps using node.js.

Testing With Node.JS Shell

Let’s start with the node command as follow and get its output result to see if Node.JS is fully functional.

REPL For Your NodeJS Apps

REPL is the Node.js shell, any valid Javascript which can be written in a script can be passed to the REPL. So let’s see how REPL works with NodeJS.

Here is the list of command line help that we can use to work with REPL.
