"uninitialized constant Authlogic"

authlogic, ruby, ruby-on-rails

Solution

Is it in your `environment.rb` file? If it is, did you restart your server?

If you're using Rails 3, is it in your `Gemfile`, and did you restart your server?

Most of all, did you install the gem?

Problem

Just followed the Authlogic tutorial. I am getting "uninitialized constant Authlogic" when I try run the app. After searching, I can see that it has to do with gems/plugins but I can't find a solution. Edit: My UserSession model is: ``` class UserSession < Authlogic::Session::Base end ```
