Stack -nix build complains about ghc version mismatch

Question

When creating three penny gui on NixOS with stack --nix build, I got an error saying that I have the wrong version of ghc. Then I tried stack --nix setup, which does not start, because bash is on an unexpected path in NixOS (this was expected, since stack --nix buildnot is mentioned in the glass documentation setup). What am I missing?

FYI, to solve zlib problems I also added shell.nix and default.nix for https://github.com/commercialhaskell/stack/issues/2130

EDIT: managed to build using the method suggested by mkkeankylej from the above link, i.e. by editing ~/.stack/config.yamland adding zlib in buildInputsto shell.nix. But I would still like to know if there is a way to make it not return to nix-shell? It looks like it stack --nix buildshould work as long as the nix-shell method does.
