• I'd be willing to implement a fix

Describe the bug

cli tools inside workspaces aren't able to find their modules. Each workspace has all the dependencies they need, but parcel and webpack both fail to start properly. They do not have any issue when used in a non-workspace environment.

To Reproduce

https://github.com/emiliaza/berry-repro

Using yarn workspace parcel start or yarn workspace webpack start ends up erroring by failing to find their own dependencies.

Environment:

• OS: macOS
• Node version v14.4.0
• Yarn version 2.0.0-rc.33
