4 Methods to Solve “yarn” Command Not Found 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

    apt installing yarn

  3. Verify the installation of yarn using:
    yarn –version

    checking 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

apt installing cmdtestAfter 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”

    adding yarn path variable to bashrc file

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

npm installing yarn

Note: If npm is not installed in your system, use the below command to install it first:
sudo apt install -y npm
