Record the process of installing yarn by ubuntu (package manager with shared code)

Yarn is a modern package manager used to manage dependencies of JavaScript projects. It provides a fast, secure, and reliable way to download, install, and manage the code packages required by the project. Compared with the traditional npm package manager, Yarn has improved performance and reliability and introduced some additional features.

Here are some of the key benefits Yarn offers:

1. Fast and efficient

Yarn uses the parallel download and cache mechanism to make the installation of dependent packages faster and more efficient. It can improve performance by downloading multiple packages concurrently, and uses local caches to avoid repeated downloads.

2. Safe and reliable

Yarn ensures the integrity and security of the software package by verifying and verifying the downloaded package. It uses a lock file (yarn. lock) to accurately record the version of dependencies to ensure consistency in different environments.

3. Simplify collaboration

Yarn allows you to share code and use and manage code packages with other developers. You can easily install and update dependencies and leverage Yarn's workflow and commands to build, test, and publish projects.

4. Reliable automatic dependency resolution

Yarn can intelligently resolve dependencies and automatically handle version conflicts and dependency complexity. It uses a mechanism called Resolver to manage dependencies and ensure that the package versions used in the project are compatible and can run normally.

To install Yarn on Ubuntu, we can follow the steps below:

Step 1: Add Yarn repository

Open the terminal and use the following command to add the Yarn repository to your system:

 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

Step 2: Update the package list

Run the following command to update the package list:

 sudo apt update

Step 3: Install Yarn

Run the following command to install Yarn:

 sudo apt install --no-install-recommends yarn

This installs Yarn and its dependencies.

Step 4: Verify the installation

After installation, you can verify whether Yarn is successfully installed by running the following command:

 yarn --version

If the installation is successful, the version number of Yarn will be displayed.

Now we have successfully installed Yarn on Ubuntu. You can start using Yarn to manage and build JavaScript projects.
