How do you solve the error “‘yarn’ is not recognized as an internal or external command, operable program or batch file”?

Yarn is a technology developed by Facebook as a productive replacement for npm. It merely notifies you that Yarn is not installed on your PC in your circumstance. It isn’t the guilty party.

Error happened during initialization of VM Java/lang/NoClassDefFoundError: Java/lang/Object is the source of the issue. The app could not be installed on the line of devices. It appears to be a Java installation issue.

The simplest method for you to solve the error “‘yarn’ is not recognized as an internal or external command, operable program or batch file” is installing Yarn globally. In your terminal, you only run the following command to install Yarn.

npm install -g yarn

Or you can run this command:

npm install --global yarn

After that, you need to examine whether yarn has been installed or not simply by running the command below:

yarn --version

If the command mentione above fails, Simply Open

Code and add this path to the environment variable path by going to Computer > Properties > Advanced System Setting > Environment Variables > Path edit add.

C:\Program Files (x86)\Yarn\bin\;
OR
C:\Users\Username\AppData\Local\Yarn\bin\;

Try restarting your terminal if the problem “‘yarn’ is not recognized as an internal or external command” still persists.

If that still didn’t work, try the next command:

npm config get prefix

The command will display the path location where npm stores your installed packages globally. The bin directory at the given path will contain the global packages.

If it isn’t already there, look at your operating system’s PATH environment variable and add the path in which the npm config gets prefix to command outputs.

You must restart any active command prompts for the command’s output to take effect if you add it to your PATH environment variable. The results of the npm configuration get prefix command on Windows will resemble C:\Users\Your User Name\AppData\Roaming\npm.

If you want to update the PATH on a Windows computer, first, you must click “Edit the system environment variables” after typing “env” into the start search box after you open the start search and type in env. Then you need to click “Environment Variables”. And finally, if necessary, let’s modify the Path variable and insert the results of the npm config get prefix command.

Make careful to update the placeholder for  Your_User_name with your actual username before entering the path: C:\Users\Your_User_Name\AppData\Roaming\npm.

You must restart any active command prompts for the command’s output to take effect if you add it to your PATH environment variable.

After doing that, your error will completely disappear and your program will run well without any errors.
