Help for first time contributor.

[belgattitude]

I read the contributor page and wasn't actually able to work on the berry repo. I'd like to improve a message to debug the new yarn pnp linker.

While yarn install works (btw: it deletes the .pnp.js and creates a boot-cli-dev.js right after), first command to try it out, like yarn test:unit complains with this message

> yarn test:unit
internal/modules/cjs/loader.js:883
  throw err;
  ^

Error: Cannot find module '@yarnpkg/monorepo/scripts/setup-ts-execution'

}

I guess there's more to know about in order to work on berry repo...

Anyone could help to sort this out ?

PS: the fork is https://github.com/belgattitude/berry and pulled the master branch. Linux / node 14

fetched master today, and it works now

That seems a little strange; best guess is that somehow your global Yarn was taking over the local one, although I have no idea why that would happen.
