rails : Could not load database configuration. No such file -

I cloned an app folder from a GitHub repository, and after bundle install the gems, I tried to use the rake db:setup and rake db:migrate commands, neither worked, and here is my error message:

arun997@promanager:~/workspace (master) $ rake db:setup require 'rails/all'... 2.470s Bundler.require... 7.590s rake aborted! Cannot load Rails.application.database_configuration: Could not load database configuration.

If anyone can help with i would be eternally grateful.
