I am trying to run simple RoR application with Phusion Passenger. At the moment when go to localhost I see the error from subject. In fact I don’t have any pending migration: My platform is Linux (Debian 8 Jessie 64x). My database is MySQL (gem ‘mysql2’, ‘~> 0.3.18’). I am using Ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-linux] and Rails 4.1.8.
