我正在AWS Cloud9上运行Ubuntu，并在此处进行了教程：https://www.railstutorial.org/book/toy_app#code-hello_root_route_redux
当我尝试运行时：rails generate scaffold User name:string email:string
我收到了所有我无法解码的垃圾：
ubuntu:~/environment/toy_app (master) $ rails generate scaffold User name:string email:string
Traceback (most recent call last):
