Run yarn command

Runs yarn with the given command and args.

Description

Yarn is a package manager that is compatible with the npm registry. Download your app's dependencies via yarn by using this Step.

This Step uses Corepack to automatically manage the Yarn version. The Yarn version is determined by the packageManager field in your package.json file or the .yarnrc/.yarnrc.yml configuration file.

Configuring the Step

To use the Step, you need to configure your dependencies in your package.json file.

1. (Recommended) Specify the Yarn version in your package.json:

   {
     "packageManager": "yarn@4.1.0"
   }

   If not specified, Corepack will use its default Yarn version.

2. Set a command in The yarn command to run input.

   If you leave the input blank, the Step will simply install your dependencies. You can find the other available command in yarn's documentation.

3. Set the arguments in the Arguments for running yarn commands input.

   You can specify multiple arguments. Check out the available arguments for each command in yarn's documentation.

Troubleshooting

If the Step fails, run it again with verbose logging enabled. To do so, set the Enable verbose logging input to yes. Doing so allows yarn to output more information about the command you ran.

Make sure your commands and arguments are correct, and that your packages are correctly defined in the package.json file.

Note: This Step requires Corepack to manage Yarn versions. Corepack is bundled with Node.js from 14.19.0 and 16.9.0 until 24.x. For Node.js 25+, Corepack will be automatically installed via npm if not already present.
