Yarn is a popular package manager that is widely used in the JavaScript community. It allows developers to easily manage dependencies and packages for their projects. However, there may be situations where you need to reinstall Yarn and its packages. Perhaps you’re experiencing issues with Yarn Reinstall or need to start fresh with a new installation. Whatever the reason, this guide will provide you with a step-by-step process for reinstalling Yarn and its packages.

Step 1: Uninstall Yarn

The first step in reinstalling Yarn is to uninstall the existing version. To do this, open a terminal window and enter the following command:

npm uninstall -g yarn

This command will remove the global installation of Yarn from your system. If you have installed Yarn locally for a specific project, you will need to remove it from that project as well.

Step 2: Remove Yarn’s Cache

After uninstalling Yarn, you should also remove its cache. The cache contains data that Yarn uses to speed up installations, and it can sometimes cause issues when reinstalling Yarn. To remove the cache, enter the following command:

yarn cache clean

This command will clear Yarn’s cache from your system.

Step 3: Delete Yarn Folders

In some cases, Yarn may leave behind folders after being uninstalled. To ensure a clean installation, you should delete these folders. The folders may be located in different places depending on your operating system. Here are the locations for common operating systems:

  • macOS: /usr/local/share/.cache/yarn and /usr/local/bin/yarn
  • Linux: /usr/local/share/.cache/yarn and /usr/local/bin/yarn
  • Windows: C:\Program Files (x86)\Yarn and %LOCALAPPDATA%\Yarn

Delete these folders by running the appropriate command for your operating system.

Step 4: Install Yarn

Now that you have removed the old version of Yarn and its cache, it’s time to install a fresh copy. You can install Yarn using the npm package manager by entering the following command:

npm install -g yarn

This command will install the latest version of Yarn globally on your system. If you need to install a specific version of Yarn, you can specify it by adding the version number to the command, like this:

npm install -g yarn@1.22.4

Step 5: Reinstall Packages

Once you have installed Yarn, you will need to reinstall any packages that were installed using Yarn. To do this, navigate to your project directory and enter the following command:

yarn install

This command will install all the packages listed in your package.json file.

Step 6: Verify Installation

After reinstalling Yarn and its packages, it’s a good idea to verify that everything is working correctly. You can do this by running the following commands:

yarn --version

This command will display the version of Yarn that is currently installed on your system.

yarn list

This command will display a list of all the packages that are currently installed in your project.


Reinstalling Yarn and its packages may seem like a daunting task, but it’s a relatively simple process. By following the steps outlined in this guide, you can ensure that you have a clean installation of Yarn and that your packages are up-to-date.
