yarn: command not found error [Solved]

# yarn: command not found error [Solved]

To solve the error "yarn: command not found", install the yarn package globally by running npm install -g yarn and restart your terminal.

If the command fails, run it with sudo and make sure the correct PATH is set in your system's environment variable.

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

Copied!
# 👇️ install yarn CLI globally
npm install -g yarn

# 👇️ get the package's version
yarn --version

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

Copied!
# 👇️ if you got a permissions error
sudo npm install -g yarn

# 👇️ get the package's version
yarn --version

If you got the error on Windows, follow the instructions in my 'Yarn' is not recognized as an internal or external command article.

# Adding the path to YARN to your PATH environment variable

If the error persists, try adding the path to YARN to your PATH environment variable.

Run the yarn global bin command to find where the global installation of YARN is located.

Copied!
yarn global bin

The path to yarn will likely be $HOME/.yarn/bin where $HOME evaluates to your user's directory.

Open your terminal and run the following command to add the path to YARN to your PATH environment variable.

Copied!
export PATH="$PATH:$HOME/.yarn/bin"

Now source your shell.

Copied!
# 👇️ for bash
source ~/.bashrc

# 👇️ for zsh
source ~/.zshrc

Try running the yarn --version command to verify yarn is installed.

Copied!
yarn --version

If the error persists, try to close and reopen your terminal.

If that didn't help, try to add the following line at the end of your ~/.bashrc or ~/.zshrc file.

Copied!
export PATH="$PATH:$HOME/.yarn/bin"

Rerun the source command after having done that.

Copied!
# 👇️ for bash
source ~/.bashrc

# 👇️ for zsh
source ~/.zshrc

Try running the yarn --version command to check if yarn is installed.

Copied!
yarn --version

# Update your PATH environment variable on macOS or Linux

If that doesn'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 that didn't work, try to add the path to the bin folder (from npm config get prefix) to your PATH environment variable and restart your terminal.

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

You can download the long-term supported Node.js version from the official nodejs.org website.

However, it is much easier to manage your Node.js version using NVM.

Copied!
# 👇️ install yarn CLI globally
npm install -g yarn

# 👇️ get package version
yarn --version

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.
