uninitialized constant

I’m using devise, wich works fine, now I try to use devise_invitable.

I installed it correctly, but I’m getting the error when I try to access


The error is:

Started GET “/users/invitation/new” for at 2011-07-06 20:47:07 -0300

ActionController::RoutingError (uninitialized constant Users):

Rendered /Users/Fernando/.rvm/gems/ruby-1.9.2-head/gems/actionpack-3.0.7/lib/action_dispatch/middleware/templates/rescues/routing_error.erb within rescues/layout (1.9ms)

The routes looks like ok, and I dont know why it return this error.
