还有其他人遇到此错误吗？人们会提供的任何帮助将不胜感激！

Has anyone else had this error? Any help people can offer would be much appreciated!

推荐答案

将根目录：to => yourController＃index移到ActiveAdmin.routes上方（个体）

Move the root :to => yourController#index above the ActiveAdmin.routes(self)

当您运行捆绑执行耙路径时，您会在仪表板#index上方看到yourController＃index。

When you run bundle exec rake routes you will see yourController#index above dashboard#index.

发生此问题是因为它有2条到root的路由（1条来自您的路径，1条来自Active Admin）

That problem occurs because It has 2 routes to root (1 from your and 1 from Active Admin)
