How to Install Node.js on Linux Last Updated : 08 Apr, 2025 Comments Improve Suggest changes Like Article Like Report Installing Node.js on a Linux-based operating system can vary slightly depending on your distribution. This guide will walk you through various methods to install Node.js and npm (Node Package Manager) on Linux, whether using Ubuntu, Debian, or other distributions.PrerequisitesA Linux System: such as Ubuntu, Debian, CentOS, Fedora, or any other popular distribution. The installation steps may vary slightly between distributions, but most methods work on all major Linux distros.Access to the Command Line: You will need terminal access with root or sudo privileges to install software and packages.Updated System: It’s essential that your system’s package list is up-to-date.Internet Connection: An active internet connection is required to download Node.js and npm packages.Looking to host your Node.js applications? Hostinger’s affordable VPS hosting offers an optimized environment for seamless development and deployment. With pre-configured Node.js templates on Ubuntu 22.04 and OpenLiteSpeed server support, you get a performance boost right out of the box. For beginners, Hostinger’s CloudPanel template makes Node.js app creation simple. Plus, with scalable plans, you have full control to customize your server setup, making it perfect for developers at any stage.1. Use Package ManagerFor most Linux distributions, the easiest way to install Node.js is through the default package manager. Here’s how to do it for common distributions:Steps to Install Node.js on Ubuntu/Debian Step 1: Update your systemBefore installing Node.js, make sure your package list is up to date.sudo apt updatesudo apt updateStep 2: Upgrade the systemOnce updates are installed you need to upgrade your system and to do this enter the below command.sudo apt upgradesudo apt upgradeStep 3: Install Node.jsUbuntu and Debian come with the apt package manager, which can be used to install Node.js. You can install Node.js directly from the official Ubuntu repositories.sudo apt install nodejssudo apt install nodejsStep 4: Install npmnpm is the package manager that comes bundled with Node.js. If it is not installed automatically, you can install it separately.sudp apt install npmsudp apt install npmStep 5: Verify the InstallationTo confirm that Node.js and npm are installed correctly, you can check their versions using:Type node -v and press Enter to check the Node.js version.Type npm -v and press Enter to check the npm version.Both commands should return version numbers, confirming successful installation.verify the installationsSteps to Install Node.js on CentOS/RHELStep 1: Update your systemsudo yum updateStep 2: Install Node.jsYou can install Node.js by adding the NodeSource repository:curl -sL https://rpm.nodesource.com/setup_16.x | sudo -E bash -sudo yum install -y nodejsStep 3: Verify the InstallationOpen Terminal to check the installed versions by running these commands: node -v: To check the Node.js Versionnpm -v: To check the npm versionverify the installation2. Using Node Version ManagerNVM is a popular way to install and manage multiple versions of Node.js. It's ideal if you need to use different versions of Node.js for various projects or if you want to easily upgrade or downgrade Node.js versions.Step 1: Install and Activate NVMFirst, download and install NVM using the following script:curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bashnvmOnce installed, you need to add NVM to your shell configuration. You can do this by running the following command:source ~/.bashrcbashStep 2: Install Node.js Using NVMTo install the latest LTS (Long Term Support) version of Node.js, run:nvm install --ltsSwitch Node.js VersionsIf you need to switch between multiple versions, you can list installed versions using: nvm lsTo switch to a specific version you can use: nvm use 22Step 3: Verify the InstallationYou may now verify the nodejs installation using the following command:Type node -v and press Enter to check the Node.js version.Type npm -v and press Enter to check the npm version.verify the installationsNote: Both commands should return version numbers, confirming successful installation.3. Install Node.js from NodeSourceNodeSource provides an up-to-date repository that ensures you get the latest version of Node.js.Note: To install NVM on your Ubuntu machine, visit the project’s GitHub page. Copy the curl command from the README file that displays on the main page to get the most recent version of the installation script.Step 1: Add NodeSource repositoryNodeSource maintains separate repositories for each version of Node.js. To install the latest version of Node.jsBefore running your actual curl command if you are not a sudo user or root user run the below command:sudo su curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -Step 2: Install Node.jsAfter adding the repository, install Node.js using apt (for Debian-based systems):sudo apt install -y nodejsStep 3: Verify Installation by node -v and npm -vUse the following command to verify the installations:node -vnpm -v4. Using SnapSnap is another method for installing Node.js on Linux, especially for those who prefer installing software in a containerized form.Step 1: Install Node.js with SnapOn Ubuntu and other distributions that support Snap, you can install Node.js directly:sudo snap install node --classicStep 2: Verify InstallationAfter installation, check the Node.js version:node -vverify the installationsConclusionInstalling Node.js on Linux is a relatively simple process, but it can vary depending on your distribution and preferred installation method. Using package managers like apt or yum is the easiest method for most users, while NVM provides greater flexibility for managing multiple Node.js versions. With these installation methods, you can easily get Node.js up and running on your Linux machine.
