any idea? sure i'm missing huge... what?

rails server specific app. started rails sever in root path, of course won't work.

you need create new app @ first.

$ rails new myapp $ cd myapp # install gems needed @ first $ bundle install # start server $ rails s 

add

from code found real reason using ruby 1.9.1. version not supported latest rails downloaded.

try upgrade ruby 1.9.3 @ least.
