Rails Generate Controller 突然决定停止工作答案

【问题描述】：

对 Rails 有点陌生，但我正在生成一些控制器，我做了一个，然后又去做另一个，它吐出一个错误：

c:\row\dev\a>rails generate controller Person name:string
C:/row/ruby200/lib/ruby/gems/2.0.0/gems/actionpack-4.0.2/lib/action_dispatch/rou
ting/mapper.rb:229:in `default_controller_and_action': missing :controller (Argu
mentError)

我尝试 rubymine 只是为了看看，它几乎只是做了同样的事情，它输出的完整列表如下。我从来没有让它决定停止生成这样的控制器，我确实在路由文件中添加了一些东西，因为我看到一个链接说路由文件可能需要 root 到：'controller#action' 虽然我从来没有将其包含在路由文件中以在之前生成控制器，但这也没有解决它。这是我在网上能找到的唯一一个有类似问题的东西。有什么想法吗？

【解决方案1】：

用于生成您指定的控制器，方法名称不是变量

喜欢

rails generate controller Person index show

我希望你能理解并且它对你有用。

谢谢。

即使我输入正确，仍然会吐出同样的错误：D
阅读此jetbrains.com/ruby/webhelp/… 它将为您提供指导。
只是为了它而生病，但这不是语法问题，我只是要重新安装 rubymine，我可以在未加载到 rubymine 的新 rails 应用程序中执行相同的命令，并且它工作正常，但该项目现在有问题，它不会生成任何控制器。
