Rails破坏控制器不起作用

Question

标题中的内容差不多。我和其他人一起做一个项目，然后将 git repo 克隆到我的计算机上，添加了一个新控制器，然后想得更好，于是跑了：

rails destroy controller requests

（requests 是控制器的名称），只得到这个无穷无尽的错误信息：

它以前工作过，那么发生了什么？我可能需要重新安装被覆盖的东西吗？

另外，任何想法为什么在粘贴我正在学习的 Rails 教程的所有内容时出错？我不记得我的文件中的任何地方都有该文本？

谢谢

您的路线似乎有误。您的 routes.rb 中是否添加了任何新路线？如果是这样，请尝试将它们注释掉，然后运行您的命令。
