How to install Yarn on Ubuntu 18.04
In this tutorial we will guide you on how to install Yarn on your Ubuntu 18.04 system via the Yarn APT package repository. The official Yarn repository is consistently maintained and provides the most up-to-date version.
Installing Yarn on Ubuntu
Follow the steps below to install Yarn on your Ubuntu system:
The first step is to install the Yarn repository and import the repository’s GPG key. To do so, run the following commands:
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
Once the repository is added to our system, update the package index and install Yarn, with:
sudo apt update sudo apt install yarn
