Solution

  • 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"
