I have a rails app running on passenger/apache 2.2.3/RHEL. Everything was working fine until I had to restart Apache. Once I did that, I got the following message:
Missing the Rails 2.3.4 gem. Please
gem install -v=2.3.4 rails, update your
RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out
RAILS_GEM_VERSION to use the latest version installed.
I'm not sure what to do, since the app was running fine before. I did
touch restart.txt to try to restart it, deployed from Capistrano again, and removed/installed the rails gem again but nothing worked.
rails -v prints Rails 2.3.4.
