No default language could be detected for this app

I push object to heroku. Run git push heroku master.

It said:

Compressing objects: 100% (113/113), done.

I googled that, but I did not find the right way to fix it!

You can change the buildpack used by an application by setting the buildpack value. When the application is next pushed, the new buildpack will be used.

heroku buildpacks:set heroku/ruby

Each language/buildpack has a bin/detect file used to detect if it can be used for that app. That error indicates no default buildpacks were detected here.

The ruby buildpack relies on the presence of a Gemfile file at the top of your directory.

This error means that file wasn't found. Is this really a ruby project? Is it at the top of your directory or in a subfolder?
