我在圆圈中绕过终端中的“此系统上没有安装Rails”消息,但它告诉我我刚安装它。

Simons-MacBook-Pro:~ Simon$ sudo gem install rails
Successfully installed rails-5.0.2

Simons-MacBook-Pro:~ Simon$ rails -v
Rails is not currently installed on this system. To get the latest version, 
simply type:

$ sudo gem install rails

You can then rerun your "rails" command.
Simons-MacBook-Pro:~ Simon$ 

特别是我应该安装它吗?

解决了它。发现我在另一条道路上有另一个副本。删除它并将其移动到我想要创建新应用程序的同一目录中。

$sudo rails where

允许我找到它。
