[Amy de Buitléir]

I can't create build a starter project in Stack. My OS is NixOS.

$ stack --version

As shown below, `stack new` gives some warnings.

(use '--show-trace' to show detailed location information)

The `stack` command doesn't have a  `--show-trace` attribute; I suspect that suggestion is coming from GHC or cabal or something.

Hello Amy,

It looks like your NixOS doesn't have GHC 8.8.3 available (and the log shows that the suggestion comes from nix-shell run by Stack), you could see some  workarounds e.g. in https://github.com/commercialhaskell/stack/issues/2861

Kind regards,

Kirill Zaborsky
