I was having this difficulty
In Windows, rails s gives 3 different errors, I fix one and get a bunch more
So then I found this project RailsFTW I don't know if that's a good thing or a bad thing but i'm guessing it's a bad thing.
After installing that, now I can't even create a project

C:\rubyblah>
So I looked up about that error with devkit.rb
I tried

and now it's even worse

Would I be closer to solving this if I got rid of RailsFTW? I thought it might have a community of windows users that happily have it working smoothly in windows, but I see no RailsFTW forum of any kind.
