Strange error when using Rails with Passenger

Question

I get the following Passenger error:

undefined method `post_reset' for Gem:Module

Someone knows what this could mean? Thanks!

Answer 1

I've got the very same error after performing a gem pristine --all to get rid of the annoying deprecation messages introduced with the latest rubygems update.

After that my mod_passenger.so got deleted resulting in this (misleading) error message. Try restarting Apache, it won't be possible if you are having the same problem.

The solution was to once again execute passenger-install-apache2-module. After that I could restart Apache and the error was gone.

Answer 2

i tried it myself and ended up with downgrading rubygems to 1.7.2, works again!
