error: failed to push some refs to 'git@heroku.com:simple-form-app.git'

 Solution: 

Add this to your Gemfile,

group :production do
  gem 'pg'
end
group :development, :test do
  gem 'sqlite3'
end

then do a bundle then repush to heroku. You cannot use sqlite3 on Heroku - which is the cause of the error.

Thank You,
