Why does Passenger try to run system gems instead of the ones in the Gemfile?

Question

Ruby on Rails

Hello.
An error like You have already activated rack 1.6.4 but your Gemfile requires 1.6.9 in the Passenger logs. Accordingly, the application does not start.
I'm trying to set Apache + Passenger on the application. Why do these types of errors occur? The official docs say that Passenger only launches what is specified in the Gemfile and is friendly with the bundler in every possible way. Already desperate to find the cause. Help who knows.

You need to specify the path to the Ruby interpreter in the Passenger settings. Probably taken system.
