Build fails on OSX 10.15.7

[capital-G]

Currently I am trying to learn Haskell via https://github.com/kowainik/learn4haskell which has happy as dependency for testing. When I try to run the tests I get the error message

Warning: this is an unsupported build that may use different versions of
dependencies and GHC than the officially released binaries, and therefore may
not behave identically.  If you encounter problems, please try the latest
official build by running 'stack upgrade --force-download'.

I am pretty new to Haskell so I don't know which infos are relevant and which aren't. If you need some further information, please ask! :)

This does not look like a happy-specific issue. I would try installing GHC with nixos.org/ on macOS. That has the advantage of being strictly reproducible, while whatever error you have looks quite hard to reproduce.

Thanks for the quick advice! I got it working on my machine, see https://github.com/kowainik/learn4haskell/issues/373#issuecomment-751281882

I am unsure how to perceed here because as haskell novice I can't say what causes the bug - maybe its already fine that the error is written down here with a fix if anyone else has the problem.
