So i updated rails and this is now what i'm getting. i tried reinstalling rails and it didn't help. it's installed. this is driving me nuts.

i'm at rails 2.3.5 and ruby 1.8.7

Missing the Rails gem. Please `gem install -v= 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.

and figured it out.

thin can't cope with rack 1.1.0. uninstalled the rack 1.1.0 gem and all is well again.

Had the same problem. Thank you so much.

Yup just wasted a good hour cursing monit and env variables.

This was the problem. Rack 1.0.1 works fine with thin so far.

Morgan, I just performed a quick test and I was able to get the following

working:

a) Rails 2.3.5, Ruby 1.9.1/1.9.2, Rack 1.1.0, and Thin 1.2.7

b) Rails 3.0 b, Ruby 1.9.1/1.9.2, Rack 1.1.0, and Thin 1.2.7

Thus, I’ll be happy to send you my test Rails app for (a) above.

Make sure you don't have gems installed in different places. We were getting this when run from rc.local because a couple gems had gotten installed in a user directory (~/.gem) instead of the system path.

I wish gem wouldn't install in a home directory unless you specifically told it to do so.

Forgot; use: gem list -d to see where things are installed
