In this guide, we'll walk you through the steps to install Yarn on CentOS 7
If you're a web developer working on CentOS 7, you might want to consider using Yarn as your package manager.
Yarn is the most popular node JS package manager that is also compatible with npm. It assists in automating the installation, configuration, and removal of superfluous npm packages. Yarn is faster than npm in terms of package installation speed and can install several packages at the same time. As a result, it is preferred over npm.
The installation procedure is relatively identical to other CentOS vesions, as well as Fedora and RHEL distributions.
Step 1: Update Your System
Before we begin, let's make sure that our system is up to date. Open a terminal window and run the following command:
sudo yum clean all && sudo yum -y update
This command will update the package list and upgrade any outdated packages on your system.
Step 2: Install Node.js
Yarn is built on top of Node.js, so you'll need to install it before you can install Yarn. Run the following command to install Node.js:
curl --silent --location https://rpm.nodesource.com/setup_12.x | sudo bash -
Install the Node.js package by typing:
sudo yum install nodejs
Step 3: Install Yarn
Now that we have Node.js installed, we can install Yarn. There are two ways to install Yarn on CentOS 7: using the official Yarn repository, or using npm.
Option 1: Installing Yarn from the Official Repository
To install Yarn from the official repository, run the following commands:
curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
