Seems like everything worked fine when I pushed to Heroku as shown below. Then I run into an error on the latter while following Heroku's Docs: http://devcenter.heroku.com/articles/ruby#install_the_heroku_commandline_client

How is there no Cedar-support detected when the Gemfile and Procfile are both in there?
Also, nothing appears on the heroku webpage.
Works fine for me--double check your Procfile is up to date on Heroku. Here's the output of my push:

I cloned my app on Github, deleted my original Heroku app, and created a new one. Now I have it running! My conclusion is that the original Heroku app was created before I made all the new changes, and commits just weren't getting updated or pushed properly somehow. By creating a new app, I don't lose a thing since the code is the same, and Heroku allows for abundant app creations. I suspect this had something to do with git remote issues that I had not taken account for.

I’m updating the environment on Heroku and one of the buildpack we use is based on Ruby, which is no longer available by default in the new heroku-22 environment/stack (nor required by our PHP app).
From the docs:
[...] end users should add the Ruby buildpack prior to the buildpack in question (they will also need to ensure minimal Gemfile / Gemfile.lock files exist, so that the Ruby buildpack passes detection).
However I have no clue what those files should include as I have zero experience with Ruby. What would be a valid set of minimal Gemfiles to trigger Ruby installation on Heroku?
I suggest you don't use that buildpack at all. It's ancient, and third-party buildpacks are always a bit questionable, even if it's just because they often stop getting updated.
Here's what it claims to do:
This is a Heroku buildpack for vendoring just the mysql binary from the mysql-client-core deb package.
If you just need a mysql binary, you can use the apt buildpack to install it without worrying about Ruby or anything like that.
Add it as your first buildpack:
heroku buildpacks:add --index 1 heroku-community/apt
Create an Aptfile in the root directory of your project that lists the Ubuntu packages you wish to install, e.g.
mysql-client-core-8.0
Note that the buildpack does not do dependency resolution. If any packages you list have their own dependencies you may have to list them explicitly.
Commit, and redeploy.
You should see the Ubuntu packages you listed get installed before your main buildpack runs.
In any case, if you really want to make your application compatible with the Ruby buildpack you should be able to simply include an empty Gemfile in the root of your project:
The Heroku Ruby Support will be applied to applications only when the application has a Gemfile in the root directory. Even if an application has no gem dependencies it should include an empty Gemfile to document that your app has no gem dependencies.
A Gemfile.lock is not required.
Note that you'll need to manually add the buildpacks you require. I believe you'll want Ruby first, then the MySQL buildpack in your question, then whatever language your application is written in, which appears to be PHP:
heroku buildpacks:set heroku/php # Main buildpack; we insert others before it below
heroku buildpacks:add --index 1 heroku/ruby
heroku buildpacks:add --index 2 https://github.com/thoughtbot/heroku-buildpack-mysql.git
heroku buildpacks
# => Should print the buildpacks in the expected order
Edited
It turns out an empty Gemfile is not enough and a Gemfile.lock is actually required as well.

An empty Gemfile will trigger the Ruby installation, however the heroku/ruby package itself does require a lock file.
The buildpack will detect your app as Ruby if it has a Gemfile and Gemfile.lock files in the root directory.
After some trial and error I figure out the following files work:
# Gemfile
source 'https://rubygems.org'
# Gemfile.lock

I have built a simple sinatra web app on my macbook. The deployment to heroku fails with the logs below. The problem is that I've already implemented their suggested fix (bundle lock --add-platform x86_64-linux) and I still get the same error message.
Any suggestions as to next steps would be very welcome. Thanks in advance.

*Update
My local repo, with x86_64-linux in Gemfile.lock, is out of sync with the remote repo on github that I have been trying to deploy from. Other files are out of date too. Concerningly, I have both pushed and pulled recently, as well as deleted the remote repo, created a new one and pushed again. Git is telling me that both the local and the remote repos are up to date with each other, when they are obviously not.
I've tried pushing directly to heroku from the command line but hit the same platform error as above.
Today, I've been trying to configure Dokku to deploy a statically-generated website of mine (built with middleman): push the middleman source to the host, generate the website on the host, and tell a nginx to serve those static files.
Following these resources 1 and 2, I setup my project with:
a .buildpacks file, containing one buildpack to build the site, and the nginx buildpack to serve the generated static HTML files:
https://github.com/heroku/heroku-buildpack-ruby.git#v222
https://github.com/dokku/buildpack-nginx.git#v14
a .static file so that the nginx buildpack knows it must serve a static website
a predeploy action in charge of building the site, using app.json :
{
"scripts": {
"dokku": {
"predeploy": "bundle exec middleman build",
}
}
}
What happened?
Apparently, at the moment I'm trying to build my middleman site with the predeploy hook, the bundle command is not available anymore. Here's an example output I'm getting:

What I tried
I noticed the first buildpack is executed, then the second one, then the predeploy hook kicks in.
I tried removing the nginx "static serve" buildpack and keep only the ruby one, and keep a bundle command in my predeploy hook. It worked and I didn't get the "command not found" error. So switching to the second buildpack seems to be messing things up for me.
I compared the path with and without the nginx "static serve" buildpack, and nothing weird. With the nginx buildpack, a new path is added but the previously set ruby paths are still there:
# with only ruby buildpack
/app/bin:/app/vendor/bundle/bin:/app/vendor/bundle/ruby/2.6.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# with both ruby & nginx buildpacks
/app/bin:/app/vendor/bundle/bin:/app/vendor/bundle/ruby/2.6.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/app/nginx
Eventually, I'm a bit lost here. Is it expected? Am I not following the dokku way? Am I getting this because of permissions issues, or something in Dokku that I'm not aware of?
For now, as a fallback, I'm serving the site by running a middleman server that receives all requests, but it makes no sense to dynamically serve a statically-generated website.
Thanks to jonrsharpe comment, I reoriented my searches and found this blog post on heroku engineering blog. Eventually, as stated by jonrsharpe:
The Nginx buildpack won't have Ruby in at all - you need to do any building in the Ruby buildpack context, so all the static buildpack needs to do is serve the results.
Therefore, to launch my middleman build command, I needed to hook somewhere in the ruby buildpack thing. And in the "jekyll on heroku" link, everything is explained: one should override the assets:precompile rake task.
Steps I followed
Add gem "rake" to my Gemfile (and bundle, of course)
Create a Rakefile with the assets:precompile task :
task "assets:precompile" do
exec("middleman build")
end
Enjoy!
I tried deploying my application today and my deployments are for the first time being rejected.
My deployment output is below. I've tried the following with no change in outcome:
Deploying with no Ruby version in Gemfile
Deploying with 2.1.0 in Gemfile
Deploying using a custom BUILDPACK_URL at https://github.com/heroku/heroku-buildpack-ruby.git
Deploying from a different branch
Deploying from a teammate's machine
Rolling back to last successfully deployed commit, changing a line in the README, committed and redeployed.
I had successfully deployed just last night. I only have made HTML and CSS changes to the new code I want to commit, so nothing in the app settings has been changed since the last successful deployment.
Why would Heroku be now rejecting my app deployments?
Thanks!

Heroku dropped support for Rails 1.9 and that was in the PATH. I had some trouble dropping the PATH because heroku had some hack where it was configured, but would not drop (probably because it was a default).
So I ended up setting the PATH to something
heroku config:set PATH=blah
and then unsetting it.
heroku config:remove PATH
That seems to have stuck.
Get the same problem as in (7) and tried all the possible answers but still couldnt get any headway. I wish you could be of help (bearing in mind that i am a newbie please). Here is the description of the problem # hand:

Based on the error, your gemfile.lock is not the same as the one in repository.
Try doing the following steps.
