我只是设置了一个新的 rails 应用程序，并使用它rails generate controller Pages来创建一个空白页面控制器，然后我添加了空的方法和视图。我将 route.rb 更改为重定向到pages/:action，所以它应该显示foo.html.erb为pages/foo. 但是，每次我尝试访问任何页面（pages/、pages/index、pages/course等）时都会出现此错误

localhost:3000/pages/register（注：实际Rails.root不同）

ArgumentError in PagesController#register
wrong number of arguments(1 for 0)

Rails.root: C:/railsapp

我尝试使用相同样式的路线重新创建您的错误，并且效果很好。我唯一能想到的可能是 register 是你的类层次结构中的一个超级方法，你已经覆盖了它？
