How to Install Node.js and npm on Ubuntu 20.04
5 min read
In this tutorial, we will explore three different ways of installing Node.js and npm on Ubuntu 20.04:
- From the standard Ubuntu repositories. This is the easiest way to install Node.js and npm on Ubuntu and should be sufficient for most use cases. The version included in the Ubuntu repositories is
- From the NodeSource repository. Use this repository if you want to install a different Node.js version than the one provided in the Ubuntu repositories. Currently, NodeSource supports Node.js
nvm(Node Version Manager). This tool allows you to have multiple Node.js versions installed on the same machine. If you are Node.js developer, then this is the preferred way of installing Node.js.
Choose the installation method that is appropriate for your environment. If you are not sure which Node.js version to install, consult the documentation of the application you’re going to deploy.
Install Node.js and npm from the Ubuntu repository
At the time of writing, the Node.js version included in the Ubuntu 20.04 repositories is
10.19.0 which is the previous TLS version.
The installation is pretty straightforward. Run the following commands to update the package index and install Node.js and npm:
sudo apt update
sudo apt install nodejs npm
The command above will install a number of packages, including the tools necessary to compile and install native addons from npm.
Once done, verify the installation by running:
Installing Node.js and npm from NodeSource
NodeSource is a company focused on providing enterprise-grade Node support. It maintains an APT repository containing multiple Node.js versions. Use this repository if your application requires a specific version of Node.js.
At the time of writing, NodeSource repository provides the following versions:
- v14.x - The latest stable version.
- v12.x - The latest LTS version.
- v10.x - The previous LTS version.
We’ll install Node.js version 14.x:
Run the following command as a user with sudo privileges to download and execute the NodeSource installation script:
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
The script will add the NodeSource signing key to your system, create an apt repository file, install all necessary packages, and refresh the apt cache.
If you need another Node.js version, for example
12.x, change the
Once the NodeSource repository is enabled, install Node.js and npm:
sudo apt install nodejs
The nodejs package contains both the
Verify that the Node.js and npm were successfully installed by printing their versions:
To be able to compile native addons from npm you’ll need to install the development tools:
sudo apt install build-essential
Installing Node.js and npm using NVM
NVM (Node Version Manager) is a bash script that allows you to manage multiple Node.js versions on a per-user basis. With NVM you can install and uninstall any Node.js version that you want to use or test.
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
Do not use
sudo as it will enable
nvm for the root user.
The script will clone the project’s repository from Github to the
=> Close and reopen your terminal to start using nvm or run the following to use it now: export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
As the output above says, you should either close and reopen the terminal or run the commands to add the path to
nvm script to the current shell session. You can do whatever is easier for you.
Once the script is in your
PATH, verify that
nvm was properly installed by typing:
To get a list of all Node.js versions that can be installed with
The command will print a huge list of all available Node.js versions.
To install the latest available version of Node.js, run:
nvm install node
The output should look something like this:
... Checksums matched! Now using node v14.2.0 (npm v6.14.4) Creating default alias: default -> node (-> v14.2.0)
Once the installation is completed, verify it by printing the Node.js version:
Let’s install two more versions, the latest LTS version and version
nvm install --lts
nvm install 10.9.0
You can list the installed Node.js versions by typing:
The output should look something like this:
> v10.9.0 v12.16.3 v14.2.0 default -> node (-> v14.2.0) node -> stable (-> v14.2.0) (default) stable -> 14.2 (-> v14.2.0) (default) iojs -> N/A (default) unstable -> N/A (default) lts/* -> lts/erbium (-> v12.16.3) lts/argon -> v4.9.1 (-> N/A) lts/boron -> v6.17.1 (-> N/A) lts/carbon -> v8.17.0 (-> N/A) lts/dubnium -> v10.20.1 (-> N/A) lts/erbium -> v12.16.3
The entry with an arrow on the right (
> v10.9.0) is the Node.js version used in the current shell session and the default version is set to
v14.2.0. Default version is the version that will be active when opening new shells.
If you want to change the currently active version enter:
nvm use 12.16.3
Now using node v12.16.3 (npm v6.14.4)
To change the default Node.js version, run the following command:
nvm alias default 12.16.3
For more detailed information about how to use the
nvm script, visit the project’s GitHub page.
We have shown you three different ways to install Node.js and npm on your Ubuntu 20.04 server. The method you choose depends on your requirements and preferences. Even though installing the packaged version from the Ubuntu or NodeSource repository is easier, the nvm method gives you more flexibility for adding and removing different Node.js versions on a per-user basis.
