Ok, I think I figured it out, BUT now It's asking me for my gitHub credentials and I can't type my credentials because I receive a 'Timeout' error.
This is what I did:
Add the remote repo to the project:
repo.git.remote({},'add','RemoteRepoName','https://github.com//.git')
Push to github
pusher = repo.git.push({:process_info => true, :progress => true}, 'RemoteRepoName', 'master')
