Passenger + Bundler - 未从已部署应用程序加载的 Gem

Question

I am trying to get a ruby app running via Phusion_Passenger (6.0.15) and Apache (2.4.54). The app is OpenProject (v12) and the system is a Raspberry PI4, but I guess this does not matter for the problem at hand.

When loading the app via Passenger I have the problem that gems are incorrectly loaded from the "system" gem list and not the openproject app vendor/bundle folder

• gems installed as given in Gemfile.lock via bundle install --deployment
• manually confirmed that the gems are indeed all correctly available in ./vendor/bundle folder
• Passenger loads and reports an error loading the app
• Looking into the errors it shows that it is incorrect versions and / or missing gems due to the fact that apparently only gems from the system wide locations (more specifically: from the user space gems that are also around) are pulled, not from vendor/bundle
• Passenger bundler/setup seems to be working somehow but something is wrong with the load paths apparently
• looking at "activated_gems" from the log files (Passenger friendly error pages) it shows that it is all the wrong versions, ie not from vendor/bundle; if I remove a gem from the default, it then also disappears from the "activated_gems"
• user and users rights seem to be correct; passenger reports the user ("openproject") under which the app should be running, vendor/bundle directories and sub-folders are owned by this user and accessible

Below are some more details from the error pages / log provided by passenger

Are there any ideas what could be wrong and causing passenger bundler to not pick up the gems from the vendor/bundle folder?

Answer 1

Ok, in the end I figured it out. Probably more of a workaround. Also according to the documentation I have read it should not have been necessary, but anyways.

Adding

SetEnv GEM_PATH /home/openproject/openproject/vendor/bundle/ruby/3.1.0

to /etc/apache2/sites-available/openproject.conf
