Error trying to use the cache option with yarn v4 and above

Description:
Throws an error:
This project's package.json defines "packageManager": "[email protected]". However the current global version of Yarn is 1.22.21.

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

Yarn: v4.0.2

Repro steps:

• Upgrade the yarn version in the project to v4 or above which doesn't include the yarn binary in .yarn/releases/
• Use the cache option along with this action
• It should spit out the error I mentioned above.

Underneath the error message you posted was the following hint.

Presence of the "packageManager" field indicates that the project is meant to be used with Corepack, a tool included by default with all official Node.js distributions starting from 16.9 and 14.19.
Corepack must currently be enabled by running corepack enable in your terminal. For more information, check out https://yarnpkg.com/corepack.

After which I enabled corepack using the command

corepack enable

And that fixed my issue.

Hello everyone. For now I'm going to close the issue as duplicate of #899. If you have any concerns feel free to ping us.

in your yaml workflow file add:

      - name: Enable Corepack
        run: corepack enable
