How To Install Yarn on Debian 9 Stretch

In this tutorial, we will show you how to install Yarn on Debian 9. For those of you who didn’t know, Yarn is an advanced package management software for Node.js applications. It is a fast, secure, and reliable alternative that any other Nodejs package manager.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Yarn on a Debian 9 (Stretch) server.

Prerequisites

• A server running one of the following operating systems: Debian 9 (Stretch).
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Yarn on Debian 9 Stretch

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt-get commands in the terminal:

apt update
apt upgrade

Step 2. Installing Yarn on Debian.

First, Yarn repository and import the repository’s GPG key:

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

After importing the key add the Yarn APT repository using the following command:

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

Next, update the package index and install Yarn using the following command:

sudo apt update
sudo apt install yarn

If using nvm you can avoid the node installation by doing:

sudo apt install --no-install-recommends yarn

Now confirm installation and check the version of Yarn:

yarn --version

Step 3. Using Yarn.

Create a new Yarn project use yarn init:

yarn init my_yarn_meilana

Adding dependency:

yarn add [package_name]

Upgrading dependency:

yarn upgrade [package_name]
yarn upgrade [package_name]@[version_or_tag]

Installing all project dependencies:

yarn
