Rails 3 Devise or Authlogic - Production Env Mysteriously Can't See Gem? Works on Dev

This problem is probably very easy to solve but somehow I cannot find a solution.

This happens for BOTH Authlogic and Devise. I have been banging my head against the wall so long that I actually ripped out Authlogic and restarted with Devise -- but experience same problem.

On dev everything is fine.

However, when I get to production, I get this whenever I try to rake db:seed or run the console. This also shows me restarting the server and my gemfile.

Why can't production see the gem? It seems to be able to see the other gems just fine.

The gem you see is the Github version -- this was a recommended fix that does not work for me. I get the same result with the default version, and with forcing a specific version.

The fact that both Authlogic and Devise have the same problem seems to indicate there is some problem with my config on production? What could it be other than the Gemfile?

Dev - Rails 3.0.4, 1.9.2p136 Prod - Rails 3.0.4, 1.9.2p0

Last resort would be upgrading Ruby so they match, but I doubt this is the problem and it would be a lot of work for some reasons 开发者_JS百科I won't go into here.

Any chance that....

1. You have not run bundle in the production environment (less likely)
2. you have your gemfile divided into groups - you would see something like this

Gemfile

group :development do
     gem 'devise'
end

The problem turned out to be that there was another rails app installed on this slice, and rake/rails was trying to call the other app's rake/rails script when run due to a misconfiguration.

The problem was resolved in the short term by forcing the rails script in the /script directory of my app. E.g.

ruby script/rails console

instead of

rails console

However, I did not find a way to easily force my own copy of rake.
