I wanted to play around on ruby and got windows 8 machine im using these tutorial but I cant get past the installation part .I have installed ruby 2.0.0 and the dev kit(DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe) but now every time i enter ruby dk.rb init in the comand prompt all I get is no such file or directory.
