IntelliJ IDEA 2018.2 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, IntelliJ IDEA suggests to install it.

Notes and limitations

  • Raptor support is available for macOS and Linux systems.

  • IntelliJ IDEA 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.
