i not re-install redmine because other users using it.

please give idea solve problem.

the paths indicate different versions of ruby in use.

• when run ruby -v command line, it's showing 1.8.7
• your passengerroot indicates 2.0.0 in /usr/local/lib/ruby/gems/2.0.0/gems/passenger-4.0.38 (the directory under gems indicates ruby version gem built for)
• the error message @ top indicates ruby_version = 1.9.3

your best course of action uninstall unneeded ruby versions, reinstall passenger , redmine.
