How to downgrade to Passenger 2.2.15?

I am using Passenger 3.0.5. For some reasons, I want to downgrade to Passenger 2.2.15. Is ther开发者_StackOverflow社区e any convenient way to do that?

Yes, uninstall passenger 3.0.5 using the gem uninstall command and then install version 2.2.15.

gem uninstall passenger
gem install passenger -v 2.2.15

You can then proceed to install the apache or nginx modules or simply use the standalone version of passenger.
