I am unable to get ‘rake gems’ to run in my test environment. I am using the following command: rake gems RAILS\_ENV=test and getting the error below. rake gems RAILS\_ENV=development works ok. Any thoughts appreciated.

I’ve now discovered this problem is being caused by a require statement in my models: require ‘list’ where ‘list’ is list.rb in the acts\_as\_list plugin. I am unable to remove this as it is needed by a standalone Ruby program that uses the same models as the Rails environment (and ActiveRecord). I still don’t understand why ‘rake gems’ works in development but not in test - that is, rake gems only complains about the “require ‘list’” statement when run in test. Any thoughts appreciated. ---

I have solved this problem by extending the load path in environment.rb: config.load\_paths += %W( #{RAILS\_ROOT}/vendor/plugins/acts\_as\_list/lib/ active\_record/acts ) rake gems RAILS\_ENV=test is now able to resolve my “require ‘list’” statements in my models. ---

The problem you ran into was the same one as this thread: [http://groups.google.com/group/rubyonrails-talk/browse\_thread/thread/e87b901813a541a5?hl=en](http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/e87b901813a541a5?hl=en) and both are caused by load\_application\_classes trying to load all your models at startup. That routine does nothing when config.cache\_classes is false (the default in development mode). However, I’m surprised that “require ‘list’” _ever_ worked. Even with the Rails environment loaded, it gives me an error. The correct require would be ‘active\_record/acts/list’. On a somewhat related note, I’ve found that Rake tasks work a lot better than standalone Ruby programs, and save a lot of headaches with loading the environment… –Matt J.
