Encountering the “bash: yarn: command not found” error is a common issue among developers working with Node.js and JavaScript projects. This error occurs when the Yarn package manager is not installed or properly configured on the system. Let’s see how to solve this error.

Reasons for “yarn” Command Not Found Error

Some common reasons for yarn command not found error are:

• Yarn not Installed: If the “yarn” command is not found, it might be because Yarn is not installed on your system.
• Incorrect Installation Path: Yarn might not be in your system’s PATH.
• Shell Session Not Refreshed: If Yarn was recently installed, the shell session might need to be restarted for the changes to take effect.
• Installation Issues: The Yarn installation might not have been completed successfully, resulting in the absence of the “yarn” command.

4 Methods to Solve “yarn” Command Not Found in Bash

Follow the below methods to solve the yarn command not found error in Bash:

1. Install “yarn” Using APT

APT can install “yarn” on your system with all its dependencies. To do that, follow the steps:

1. Press CTRL+ALT+T to open the terminal.
2. Run the command:

   sudo apt install -y yarn

   

3. Verify the installation of yarn using:

   yarn –version

   

Thus you can resolve the command not found error regarding yarn.

2. Install “cmdtest”

CMDtest is a cross-platform software testing framework for executing and managing functional test suites in various computing environments. Installing cmdtest is a way to resolve yarn-related errors. To install “cmdtest”, open the terminal and run:

sudo apt install -y cmdtest

After that, the “yarn command not found” error will be resolved.

3. Set “yarn” PATH Variable

A prevalent reason behind the “yarn command not found” is Yarn is not present in your system PATH environment variables. To set the PATH variable for yarn, follow the steps below:

1. Press CTRL+ALT+T to open the terminal.
2. Open bashrc file using:

   nano ~/.bashrc

3. Paste the below line at the end of the file:

   export PATH=”$PATH:$HOME/<user name>/.yarn/bin”

   

   Replace <user name> in the above command with the username of your Linux. You can check this using whoami command.
4. Press CTRL+S to save, and CTRL+X to exit.
5. Now, execute the bashrc file using:

   source ~/.bashrc

   

After that, the “yarn command not found” error will be resolved.

4. Install “yarn” Using NPM

Node Package Manager (npm) is the default package manager for the JavaScript runtime environment Node.js. You can use npm to install, share, and manage packages and dependencies in your projects. If npm is already installed on your system, you can use it to install Yarn globally by running the following command in your terminal or command prompt:

npm install -g yarn

sudo apt install -y npm

Conclusion

In conclusion, the ‘bash yarn command not found’ error signals a challenge in accessing the Yarn package manager within the Bash environment. Resolving this issue involves installing Yarn separately.
