Hi! I’m on macOS Monterey, intel core.

I have tried uninstalling (ghcup nuke, removed xcode’s command line tools, removed .ghc, .cabal and .ghcup folders) and reinstalled xcode-select and then:

Installing GHC / GHCup

Request for help

Does anyone know what I could try to make things work again? Thank you. :pray:t2:

/usr/local/Cellar is used by homebrew. My guess is that you have a somehow broken homebrew install, and GHC is picking up awk from there. (Whether for good reason or not I can’t say.) I think what I’d to to investigate further is to try running awk and gawk from the terminal, see if they’re the ones from homebrew, etc., and maybe try rerunning the ghcup installer in a terminal where /usr/local is removed from the path…

Thanks so much!
I got further after a brew cleanup of gawk. Now (curl) install ends with the following:

 Installing cabal
[ Info  ] Cabal installation successful
sh: line 119: cabal: command not found
"cabal update --ignore-project" failed!

and so, after brew installing ghc and cabal, it all works out!

That doesn’t sound right. You have now GHC and cabal from brew and from GHCup.

It sounds like something is weird about your shell configuration.
