[Bug] `yarn workspaces foreach exec` fails

• I’d be willing to implement a fix

Describe the bug

yarn workspaces foreach exec fails

To Reproduce

I am trying to run depcheck in every workspace, but it seems that exec, while a valid yarn command, is not passed through by yarn workspaces foreach. Is this a bug or is exec not meant to be supported?

yarn workspaces foreach exec depcheck

Usage Error: Invalid subcommand name for iteration - use the 'run' keyword if you wish to execute a script

@DerekZiemba You’re using Yarn Classic (v1), while yarn workpaces foreach is a Yarn 2 feature. You can consult the installation guide to install Yarn 2. If it still doesn’t work, you should probably open another issue, as it’s unlikely it would be related to this one.

Yeah, but yarn workspaces foreach run depcheck won’t do a thing unless there are depcheck scripts in all workspaces. Is that expected behaviour?

It will skip over scripts that don’t declare a script of this name, yes. However it probably should execute it too if there’s a binary of the specified name, so if it doesn’t do so already I’d see that as a bug.
