Ruby-heroku No default language could be detected for this app

Question

I want to use Heroku for my Ruby apps (not on Rails).

I wrote a Twitch chat bot but I can't deploy it.

Here is the code: https://github.com/sydneyfunnelAIO/sydneybt

I tried add buildpacks but I got this warning when I tried to deploy:

App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/ruby.tgz

Do you have a `Gemfile` and `Gemfile.lock` committed to the root of your repository? — Chris, Sep 14 '19 at 21:29
On Stack Overflow questions should be self-contained. Generally speaking, we're not going to go off-site to find critical information. Having said that, I took a look and found that in fact you _don't_ have those files. I'll add an answer. — Chris, Sep 14 '19 at 21:35

Gemfile and gemfile are different things. Rename gemfile to Gemfile and gemfile.lock to Gemfile.lock, commit that change, and deploy again.

If you're using a filesystem that doesn't distinguish between those things (like most Windows filesystems) it might be tricky to do. See Change case of a file on Windows?
