Build failed with NonZeroExit 77

hello - i'm picking up Tidal Cycles again after a bit of break. I went to reinstall the 'easy' mac package and keep getting this -

[ Info ] verifying digest of: ghc-8.8.3-x86_64-apple-darwin.tar.xz

[ Error ] Build failed with NonZeroExit 77 "./configure" ["--prefix=/Users/LindsayCorstorphine/.ghcup/ghc/8.8.3"]

What does it mean and what do I do from here?! Help!

Thanks!

Hi @Lindsay_Corstorphine,
Hm it's having problems compiling some library from source code. Maybe the compiler is missing.

What happens when you run this in a terminal window:

xcode-select --install
