'Yarn' is not recognized as an internal or external command #

To solve the error "'yarn' is not recognized as an internal or external command, operable program or batch file", install the yarn package globally by running npm install -g yarn, restart your terminal and make sure your PATH environment variable is set up correctly.

Open your terminal and install yarn globally by running the following command.

Copied!

# 👇️ install yarn cli globally npm install -g yarn # 👇️ get package version yarn --version

If you see a package version output from the second command, then yarn is installed successfully.

If the global installation of yarn fails, you might have to open your shell as an administrator or run the command prefixed with sudo.

Copied!

# 👇️ if you got permissions error sudo npm install -g yarn # 👇️ get package version yarn --version

If the "'yarn' is not recognized as an internal or external command" error is not resolved, try restarting your terminal.

If that didn't help, run the following command:

Copied!

npm config get prefix

The command will show you the path where npm puts your globally installed packages. The global packages will be in the bin directory at the specified path.

Look at the PATH environment variable on your operating system and add the path that the npm config get prefix command outputs, if it's not already there.

If you add the output from the command to your PATH environment variable, you have to restart any open command prompts before it takes effect.

On Windows, the output of the npm config get prefix command will look something like: C:\Users\Your_User_Name\AppData\Roaming\npm.

To update the PATH on a Windows machine, you have to:

Open the start search and type in env and then click "Edit the system environment variables"
Then click "Environment Variables"
Edit the Path variable and add the output you got from the npm config get prefix command.

The path should look like C:\Users\Your_User_Name\AppData\Roaming\npm (make sure to replace the Your_User_name placeholder with your actual username).

If you add the output from the command to your PATH environment variable, you have to restart any open command prompts before it takes effect.

If you get the error "yarn.ps1 cannot be loaded because running scripts is disabled on this system", open your PowerShell as an administrator and set its execution policy with the Set-ExecutionPolicy command.

Copied!

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Make sure to open your PowerShell as an administrator before you run the Set-ExecutionPolicy command.

This effectively removes the execution policy of Restricted, which doesn't allow us to load configuration files or run scripts. The Restricted execution policy is the default for Windows client computers.

If you are on macOS, you can update your path with the following command:

Copied!

# make sure path matches with npm config get prefix export PATH=/usr/local/share/npm/bin:$PATH

If you are on Linux, you can add the output from the npm config get prefix command to your .bashrc file.

Copied!

# 👇️ make sure to update the path with the output # from the command export PATH="/usr/local/share/npm/bin:$PATH"

If you add the output from the command to your PATH environment variable, you have to restart any open command prompts before it takes effect.

If that doesn't help try to reinstall Node.js on your machine and then install yarn globally by running npm install -g yarn.

During the installation you might get a prompt for whether you want to automatically update the PATH environment variable on your system, make sure to tick the option.

Copied!

# 👇️ install yarn cli globally npm install -g yarn # 👇️ get package version yarn --version

If the global installation of yarn fails, you might have to open your shell as an administrator or run the command prefixed with sudo.

Copied!

# 👇️ if you got permissions error sudo npm install -g yarn # 👇️ get package version yarn --version

Alternatively, you can see how you can fix the permissions error on this page in the official npm docs.
