Cannot use nix support on OSX

Languages Nix

I am trying to combine language: nix and nix: 2.2.1 with os: osx , but the nix installer fails:

Is this expected to work?

Work-around:

      os: osx
      language: generic
      before_install:
      - curl https://nixos.org/nix/install | sh
      - source /Users/travis/.nix-profile/etc/profile.d/nix.sh

iirc the old darwin installer was not multi-user by default, while Nix 2.2.1 is. So there’s some fiddling around to get that working with newer Nix I’m afraid (until someone fixes travis setup).
