Additional context

I'm confused by the exact triggering conditions, though something to do with the ruby-audio gem seems to cause it. The demo project has the ruby-audio gem installed from github, and the akismet gem. The akismet gem is randomly chosen, but it seems to need at least 2 gems in the gemfile to trigger this bug. If I install ruby-audio from rubygems, the problem goes away.

Hello, I'm a bot and I thank you in the name of the community for opening this issue.

To help our human contributors focus on the most-relevant reports, I check up on old issues to see if they're still relevant. This issue has had no activity for 180 days, and so I marked it as stale, but you can rest assured it will never be closed by a non-human.

The community would appreciate your effort in checking if the issue is still valid. If it isn't, please close it.

If the issue persists, and you'd like to remove the stale label, you simply need to leave a comment. Your comment can be as simple as "still important to me". If you'd like it to get more attention, you can ask for help by searching for maintainers and people that previously touched related code and @ mention them in a comment. You can use Git blame or GitHub's web interface on the relevant files to find them.

Lastly, you can always ask for help at our Discourse Forum or at #nixos' IRC channel.

I found a hacky workaround, but would be interested in the proper fix.

Here I delete the bundle & bundler executables from the bundlerEnv output. It seems like they conflict in weird ways with the ones that the wrappedRuby derivation supplies. https://github.com/jdelStrother/nix-bundler/commit/edd53369dd87bfec043638ddc081e34e76a6686b
