“导轨生成控制器”错误

Question

Does anyone know what this error means? I typed this same command before and it worked perfectly, but then I destroyed the controller and set my secret-key. That was all I did to my app. After that, I get this error everytime I try to create a new controller.

当您键入“ rvm gemset list”时，您会看到什么？
