Heroku does not accept push even though I have sqlite in development block

Question

I have the following lines in my Gemfile:

gem \'rails\', \'3.1.1\'

group :production do
  gem \'pg\'
end        

group :development, :test do
         


        

Answer 1

Hoppla. I made quite a silly mistake here. I was currently working on a branch but I pushed the master branch to Herokum, like I was used to.

So git push heroku master did push an old version of the branch, which did of course not contain my changes to the Gemfile.
