Heroku is bundle installing Sqlite, despite Gemfile specifying for development only - sqlite

Question

When I attempt to push to heroku with git push heroku master I receive the error:
Counting objects: 55, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (43/43), done.
Writing objects: 100% (43/43), 4.01 KiB, done.

As you can see, the bundle install excludes development and tests (or so it appears at the top), and my gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.1'
gem 'bootstrap-sass', '2.0.0'
gem 'bcrypt-ruby', '3.0.1'
gem 'faker', '1.0.1'
gem 'will_paginate', '3.0.3'
gem 'bootstrap-will_paginate', '0.0.5'
gem 'taps'
group :production do
gem 'pg', '0.12.2'
end
group :development do
gem 'sqlite3', '1.3.5'
gem 'annotate', '~> 2.4.1.beta'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.4'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.0'
group :test, :development do
gem 'rspec-rails', '~> 2.8.rc'
gem 'guard-rspec', '0.5.5'
gem 'guard-spork', '0.3.2'
gem 'spork', '0.9.0'
end
group :test do
gem 'capybara', '1.1.2'
gem 'factory_girl_rails', '1.4.0'
gem 'cucumber-rails', '1.2.1'
gem 'database_cleaner', '0.7.0'
end
#Nifty Scaffold
gem 'nifty-generators', :group => :development
# Location - Geocoder
gem 'geocoder'
gem "mocha", :group => :test
Yet you can still see that the bundle is trying to install sqlite, and thus failing. Any idea what could be going wrong? Many thanks.

Answer 1

I had this problem. After a bit of head-scratching, I realized after I made changes to my Gemfile, I forgot to run git commit, before pushing to heroku.
