[Nix-dev] mix bundlerEnv and python3.buildEnv

[Maksim Bronsky]

Hi,

just as a follow-up how I solved it:

I changed the postPatch hook to explicitly substitute the shebang with the version I included as a buildInput:

sensu-plugins-mongodb = attrs: {
      buildInputs = [ pyenv ];
      postPatch = ''
        # the ruby check runs a python script
        # patchShebangs bin/check-mongodb.py
        substituteInPlace bin/check-mongodb.py \
        --replace "#!/usr/bin/env python" "#!${pyenv}/bin/python"
      '';
    };
