git - remote rejected master -> master (pre-receive hook declined)

Question

I'm working in rails 3.2 and I receive an error when I try to push to heroku:

 git push heroku master
Counting objects: 496, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (435/435), done.
Writing objects: 100% (496/496), 5.17 MiB | 249 KiB/s, done.
Total 496 (delta 125), reused 216 (delta 8)

-----> Heroku receiving push
-----> Removing .DS_Store files
 !     Heroku push rejected, no Cedar-supported app detected

To git@heroku.com:lumeo.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:lumeo.git'

I have tried the few methods recommended on this forum, including emptying and reinstalling the Gems and deleting and adding the remote, to no avail.

any suggestions?

Answer 1

Make sure that your Rails app is in the root of the repo, the Gemfile is present and properly named. It is basically not able to detect your code base as one of the supported project types and hence failing it. Also, even if you do have a proper project, make sure it is part of the repository and you have committed it fine (git status will help you here and a ls should help you verify the project structure).
