I've been stuck on this problem since yesterday now, I've scoured the internet and it seems a lot of people have had this same error after running 'rails generate devise User'
I'm running what I believe to be the latest version of Devise (3.0.0.rc) and when I try to run 'rails server', I get the below error message. (I followed the insructions given by devise upon install)
I can't destroy the model, I can't migrate my db and I have to delete the whole project and start again every time.
Please help!
