Can't install on Nixos

[qrilka]

Probably that could be filed to nixpkgs repo but maybe it's something of a known issue.
I'm using nixos-18.03, trying to install stackage2nix with nix-env -f "<nixpkgs>" -i -A haskellPackages.stackage2nix, fails with

As I understand #57 fixes that, but why isn't it fixed in nixpkgs?

stackage2nix build is only tested against a specific haskell packages set, based on Stackage LTS.

To install stackage2nix, please use the Stackage overlay https://github.com/typeable/nixpkgs-stackage or the nix expression from this repo https://github.com/typeable/stackage2nix#stackage2nix-wrapper

Thanks, does it mean that stackage2nix should be excluded from nixpkgs?

It could be, if no one is interested in maintaining it.
