Hi Bahram. ' DL is deprecated, please use Fiddle ' is actually a warning. The warning message comes out when you require 'irb' ( because irb require 'readline' ) or anything else wants to require 'readline'. If you feel it's annoying, you can comment out it at C:\Ruby200\lib\ruby\2.0.0\dl.rb.

I still don't know how to solve it, I have exactly the same problem. What do I have to do? Each time that I write :

/bundle exec rails server

I got the same answer:

DL is deprecated, please use Fiddle. c:/users/portatil/documents/gemfile not found

Hi Gabrial, As Tuan Pham said just comment out it at C:\Ruby200\lib\ruby\2.0.0\dl.rb that is all.

Thanks for the answer, I was not getting the "comment out", but when I do it now I have another problem, that's what appear in the cmd screen and I do not understand at all what is not working here.
