I believe the problem is that heroku does not support mysql out of the box. You will need to switch over to Postgres or use an addon, for example ClearDB.

Update: On second thought it is probably this

The error message you're getting regarding Gemfile.lock may be because your Gemfile and Gemfile.lock don't agree with each other. It sounds like you've changed something in your Gemfile since you last ran bundle install (or update). When you bundle install, it updates your Gemfile.lock with any changes you've made to Gemfile.

Make sure you run bundle install locally, and check-in to source control your newly updated Gemfile.lock after that. Then try deploying.

Edit: As recognised in the comments, a conditional in the Gemfile resulted in a valid Gemfile.lock on one platform, invalid on another. Providing a :platform flag for these platform-dependent gems in the Gemfile should solve the asymmetry.

You skipped part of the installation instructions, namely:

We need to switch the Gemfile.lock to PostgreSQL. Edit Gemfile and change ENV['DB'] ||= 'mysql' to ENV['DB'] ||= 'postgres'. Then run: 

bundle --without development test heroku production assets
git add Gemfile Gemfile.lock
git commit -m "switch Gemfile.lock to pg exclusivly"
