How to Install Node.js and NPM on Ubuntu 18.04

сентября 27, 2019 • Atta ✨

Node.js is an open-source, cross-platform, asynchronous JavaScript run-time environment that executes JavaScript code on the server-side. This means that you can run JavaScript code on the server as a standalone application without involving any browser. Node.js is designed to develop high-performance and scalable network applications.

The main strength of Node.js lies in an event-driven, non-blocking I/O model that makes it lightweight and efficient.

Node Package Manager (NPM) is the default package manager for Node.js and the largest ecosystem of open source libraries in the world.

In this article, you will learn how to install Node.js and NPM on Ubuntu 18.04. The same instructions apply for any Ubuntu-based distribution like Kubuntu, Linux Mint, and Elementary OS.

There are several ways to install Node.js on a Ubuntu 18.04 server depending on your environment and needs. Here we will show you the three simplest and most efficient ways.

Prerequisites

Installing Node.js and NPM from Ubuntu Repository

The simplest and fastest way to install Node.js and npm on a Ubuntu 18.04 server is through the official distribution repository. Both Node.js and npm packages are included in default Ubuntu repositories.

At the time of writing this article, the Node.js version included in the Ubuntu repositories is 8.10.0 which is the last LTS version.

To install this version, you can use the apt package manager. Let us start with refreshing the local package index by running the following command:

Next, execute the following command to install Node.js and npm:

That’s it. You have successfully installed both Node.js and npm on your Ubuntu 18.04 server.

You can now check which versions of Node.js and npm are installed by typing:

You will see the following output:

Although the Node.js version installed through this method is not the latest LTS release, this is the easiest and faster way of getting started with Node.js and npm.

Installing Node.js and NPM using NVM

Ab alternative to installing Node.js through apt package manager is to use NVM (Node Version Manager) tool. NVM is a bash script that is used to install and manage multiple Node.js versions on the same machine.

Through NVM, you can quickly add or remove any Node.js version to your Ubuntu 18.04 machine — something really helpful for testing the code on a specific Node.js version. You can easily switch between an LTS version and the latest available release.

Follow the below steps to install Node.js and npm through NVM.

Step 1 — Install NVM Script

Let us download and install the NVM script by running the following command:

The above command will copy the NVM repository contents from GitHub to the

/.nvm directory on your local file system. It will also update your

The next step is to either log out and log back in or load the changes made to your bash profile by using the source command:

Once the NVM installation is completed and the script is added to your PATH variable, you can verify it by tying the following:

You should see the following output:

Step 2 — Install Node.js and NPM

With NVM installed, you can install the latest Node.js version by running the following command:

The output should look something like below:

Verify the installation by typing:

You should see the following output:

The above command will install and switch to the latest TLS version which is v10.16.3 at the time of writing. You should always use this version in a production environment for the sake of stability and support.

To list all the available Node.js versions that you can install, type the following:

Here is how the list looks like (I have omitted the older versions):

Feel free to choose the one you want from the above list.

Let us install one more Node.js version — the previous LTS version 8.10.0 :

NVM will automatically switch to the most recently installed version. You can list all the installed versions by typing:

The output should look something like below:

To change the currently active version to LTS, type the following:

You will see the following output:

To change the default Node.js version, run the following command:

This version will be auto-selected when the next session starts. Type the following to switch to default version:

The good thing about NVM is that each installed Node.js version keeps track of its own packages. npm is also automatically installed to manage these packages. You can type the following to find the current npm version installed:

You will see the following output:

Run the following command to learn more about all the options available with NPM:

Installing Node.js and NPM from NodeSource

The 3rd and last way of installing Node.js and npm on Ubuntu 18.04 is by using the PPA (Personal Package Archive) repository maintained by NodeSource. Just like NVM, they provide up-to-date Node.js versions than the official Ubuntu repositories and allow you to select the specific Node.js version you want.

At the time of writing this article, NodeSource repository offers the following Node.js versions: v12.x, v11.x, v10.x, and v8.x.

Let us install the current LTS version of Node.js, v10.x, Dubnium.

First of all, enable the NodeSource repository by running the following curl command:

The above command will add the PPA to your configuration file, create an apt sources repository file, install all required packages, and update the apt local package cache.

After executing the setup script from NodeSource, you can install Node.js and npm packages by typing the following:

The nodejs package contains binaries for both Node.js and npm. So you do not need to separately install npm.

To verify that both Node.js and npm were installed successfully, type the following command:

You will see the following output:

To compile and install native addons from npm, you will need to install the build-essential package:

Uninstalling Node.js and NPM

Uninstall apt Packages

To remove Node.js and npm packages installed from Ubuntu’s official repositories or NodeSource PPA via apt package manager, execute the following command:

The above command will remove the packages and keep the configuration files. If you no longer need these configuration files at a later point, then run the following command:

This will uninstall both packages and remove the configuration files associated with them.

As the last step, you should run the following command to remove unused packages that were installed automatically with the removed packages:

Uninstall NVM Packages

To uninstall a Node.js version that you have added through NVM, first run the following command to determine whether the version you want to remove is the currently active version or not:

If it is not the currently active version, just typing the following:

If you want to uninstall the current active Nod.js version, you should first deactivate it by typing:

Then remove it by running the following command:

/.bashrc (or other shell resource config) and remove the following lines:

Conclusion

That’s all for folks for today. You have learned about three different ways to install Node.js and npm on your Ubuntu 18.04 server. The method that suits you the best depends on your requirements and the environment where you are going to run your Node.js code.

If you are looking to deploy Node.js applications on a production environment, then the best option is to install Node.js from the NodeSource repository.

Developers may tend to like NVM for installing Node.js as it offers more flexibility to quickly install and switch between different Node.js versions.

After it automatically clones the NVM repository and adds the NVM path to ZSH or Bash, you receive the following output:

3. Then, source the bash file by running:

4. Check whether the installation was successful by verifying nvm version:

This lists all available versions of Node.js, including the latest LTS version, like in the image below:

Note: LTS stands for long-term support and is used for software that is maintained for an extended period and is recommended as being the most stable.

6. To install a particular version, use the command nvm install and add the number of the version. For example:

To view all installed versions on your manager, use the command:

This lists all installed Node.js versions as well as the default and stable versions.

To check which version you are currently using, run the command:

To switch versions of Node.js (if you have already installed it on the NVM) enter the command:

Option 3: Install Node.js from NodeSource Repository

Alternatively, you may want to install Node.js and NPM from the NodeSource repository by adding its PPA (Personal Package Archive) for Ubuntu.

To enable the NodeSource repository, you have to use a curl command.

1. If you do not have curl on your system, run the following command to install it:

Press y to confirm the installation and hit Enter.

2. Now use the following sudo bash script to enable NodeSource:

To install another version, replace setup_12.x with the wanted version.

3. Next, install both Node.js and NPM with one command:

4. Verify the installation by checking the versions of Node.js and NPM.

Run the commands:

Note: When installing NodeSource, it is necessary to specify which version of Node.js you will install. In the example above, the Node.js version is 10, but other versions are also available.

Installing Development Tools

Once you have Node.js and NPM setup, install the development tools. This automation tool kit allows compiling and installing native add-ons from the NPM.

To install development tools run the command:

Remove Or Uninstall Node.js on Ubuntu

To remove a specific version of Node.js, run the nvm uninstall command appended by the version number.

For example, to uninstall version 8.11.1 run the command:

Как установить Node.js и npm в Ubuntu 20.04

Node.js — это кроссплатформенная среда выполнения JavaScript, построенная на JavaScript в Chrome и предназначенная для выполнения кода JavaScript на стороне сервера. Обычно он используется для создания серверных приложений, но также популярен как полнофункциональное и интерфейсное решение. npm — это менеджер пакетов по умолчанию для Node.js и крупнейшего в мире реестра программного обеспечения.

В этом руководстве мы рассмотрим три различных способа установки Node.js и npm в Ubuntu 20.04:

Выберите метод установки, подходящий для вашей среды. Если вы не уверены, какую версию Node.js установить, обратитесь к документации приложения, которое вы собираетесь развернуть.

Установите Node.js и npm из репозитория Ubuntu

How to Install Node.js and npm on Ubuntu 20.04

This article shows you how to get Node.js up and running on your Ubuntu 20.04 system using a non-root user account with sudo privileges.

There are two installation methods that we will look at:

Method 1: Installing Node.js from Ubuntu’s Official Repository

Installing Node.js with an apt package manager from Ubuntu’s official repository is fairly straightforward. First, update your package listing before running the installation command by entering the following:

Verify the install by checking the version of Node.js you have downloaded:

The process shown above should download the latest package available in Ubuntu’s software repository. To download a specific version, try out one of the other methods in this tutorial.

You can install npm just like we installed Node.js with the apt repository. Enter the following command to commence installation of npm:

You have now installed npm and Node.js on your system. You can now start using node.js and the npm library to add functionalities to the software on your system.

Method 2: Using nvm to Install Node.js

If you want to download a specific version of Node, or if you just want more customizability in the installation, using nvm in the process can do this for you. Nvm stands for Node Version Manager and is a tool that lets you administer several side-by-side and active Node. js versions on your system.

First, copy the curl command from the readme file on the GitHub page for nvm:

Paste it on the command terminal and run it to install the nvm. Then, run the following command to source your bash file.

To see what versions of Node are available to download, enter the following command:

Then, add whichever version you want to download in the following command syntax:

For example, to download v14.9.0, you would write the command as follows:

You have now successfully downloaded and installed Node.js v14.9.0 onto your system. You can download multiple different versions with nvm without the versions interrupting each other. You can even download and install long-term support versions of Node with nvm, such as Erbium or Dubnium. For example, the following command installs the latest Erbium version:

You can see all the versions of Node installed on your system by entering the following:

Use the following command to enter a different version of Node:

Nvm is a great tool to use because it brings together many options for efficient management of the Node.js software.

Wrapping Up

This tutorial looked at two different ways to install Node.js on an Ubuntu 20.04 server: by using nvm, and by directly requesting the program from the standard Ubuntu repository. If you are looking to install the latest version as quickly as possible, you should go with the first method. Otherwise, if you want more flexibility with your install, you can choose either of the two methods.
