Also tried heroku buildpack:set https://github.com/mchung/heroku-buildpack-wordpress.git

Also tried heroku stack:set cedar-10

I'm having this same issue, but I've used Heroku for several sites and this is the first time encountered it. I /think/ it is happening because Heroku can't find specific files that inform it of what buildpack to use, and even if you specify what buildpack, it will fail anyway.

If I come across a workaround I'll let you know. Have you tried using the default buildpack?

Same issue here. Tried adding a Procfile as described here: http://stackoverflow.com/questions/22808677/how-to-resolve-push-rejected-no-cedar-supported-app-detected-error-in-heroku

No luck. Any leads?

Like I said before, I had used Heroku for Rails apps before with no problem. Shortly after commenting I realized that the one I was having this issue with was a little different. This time around I had created a blank repository on GitHub then cloned it right to my desktop. THEN created the Rails App.

So inside the directory made for my repository by GitHub was a ReadMe, the application itself, and the hidden .git file. In normal circumstances, one would create their app in the console, git init from the console (putting the .git file inside the app), and then push to GitHub and onto Heroku.

Doing that alleviated the problem with the buildpack. Have you done any research into what file structure Heroku expects for the app of your type?

Ah! I just scrolled down on the stackoverflow link and saw you solved it. Congrats!
