Hi there guys! Just started messing around with a discourse instance and wanted to add authentication via slack. Found an existing plugin but it’s broken so I decided to try and patch it up however I am no ruby dev at all and don’t have an env to set up for local testing and whatnot. I’ve published my fixes to the plugin at [GitHub - Kukks/oauth-slack-discourse: Discourse plugin to sign up using slack · GitHub](https://github.com/Kukks/oauth-slack-discourse/) but the discourse builder fails on it and I’m unsure why. Can someone point me in the right direction? 🙂 The code is almost identical to the linkedin auth plugin. ---

Thanks for replying @jomaxro. Yup, that’s the one. Output below: ```plaintext Bundle complete! 111 Gemfile dependencies, 201 gems now installed. Gems in the group development were not installed.

Perhaps try using [GitHub - kmrshntr/omniauth-slack: omniauth-slack · GitHub](https://github.com/kmrshntr/omniauth-slack) instead of `ginjo-omniauth-slack`? From a quick review it seems that the `ginjo` gem is deprecated. ---

According to this thread, ginjo should be a more or less fork of that repo [https://github.com/kmrshntr/omniauth-slack/issues/63](https://github.com/kmrshntr/omniauth-slack/issues/63) ---

So it does. Sadly I can’t help much beyond that suggestion. I’ll note that it does _appear_ to eventually install successfully later in the logs. Perhaps one of the community developers could offer better suggestions.
