nix-shell fails while trying to install shopify-cli and nokogiri installation due to issues with gzdopen

[rbmdotdev]

Hi I have bundix installed using

nix-env -iA bundix

I have the following default.nix

with (import <nixpkgs> {});
let 

  gems = bundlerEnv { 
    name = "botega"; 
    gemdir = ./.;
  };

in stdenv.mkDerivation {
  name = "botega";
  buildInputs = [
    gems
    gems.wrappedRuby
  ];

}

and the following Gemfile

source 'https://rubygems.org' do
  gem 't'
  gem 'shopify-cli'
end

running `nix-shell -p bundler bundix --run 'bundle && bundix' generates a gemfile.lock and a gemset.nix for me no problem

when I run nix-shell I get a build error

If I remove shopify-cli from the gemfile nix-shell works fine and I can use t from within it no problem

I think the relevant error from mkmf.log is conftest.c:16:13: error: conflicting types for 'gzdopen' but I have included the full log below just in case

The mkm.log file for the failure is as follows:

--------------------

any ideas on how to get this working and get shopify-cli gem accessible from within a nix-shell?

edit:

I am wondering I this snippet from the nix-shell output is a clue to something being wrong because I thought pkg-config should be provided by bundix by default (as is nokogiri I guess 🤷

could really use some help on this, almost three days wasted now trying to get a usable ruby environment up and running. I think it boils down to ruby inside the nix-shell not being able to see zlib but I have added it in multiple different documented ways and just cant seem to figure this out

[milch]

I just ran into the same issue. No clue what caused it but I just removed the following directories (via SO):

rm -r ~/.nix-channels ~/.nix-defexpr ~/.nix-profile

sudo rm -r /nix

Then reinstalled nix with the multiuser installer, and that fixed it 🤷🏼

Thought I'd drop a comment here in case it helps anyone in the future.
