RubyMine 2018.1 Help

Phusion Passenger Special Notes

Phusion Passenger (including version 5 with the code name Raptor) can be selected as a Rails server in a Rails run/debug configuration.


  • The corresponding gem should be installed. If the gem is missing, RubyMine suggests to install it.

Notes and limitations

  • Raptor support is available for macOS and Linux systems.
  • RubyMine creates an initializer file config/initializers/rubymine-passenger-debug.rb.
  • Phusion Passenger initializer is used only for Phusion Passenger debugger; execution of Rails applications is not affected.
  • Use Phusion Passenger with only those settings that are specified in the console.
  • The Phusion Passenger prespawn script should load the dynamic content generated by Rails, but not a static page.
