我的应用程序在本地主机上运行没有问题，但我无法使用heroku正确部署它。我已经阅读了这里关于这个问题的所有其他问题，并尝试了许多方法来解决它，但还没有解决。
我已经在下面复制了我的heroku日志，因为我不知道如何解决这个问题。

我的管理员usercontroller.rb是
class Admin::UserController < ApplicationController
def index
end
def new
end
end
您有Admin模块或类吗？我设置了类似的控制器，比如：
controllers/文件夹中的admin_controller.rb：
class AdminController < ApplicationController
...
end
然后在controllers/admin/users_controller.rb:中为用户提供一个子控制器
class Admin::UsersController < AdminController
def index
end
def new
end
end
然后，在您的路线中，您可以适当地确定范围或名称空间：
#routes.rb
namespace :admin
resource :users
end
请参阅"控制器名称空间和路由"以了解所需的特定路由。
谢谢-我设法解决了这个问题。
当我使用activeadmin时，我与管理文件夹中不必要的user_controller.rb发生了冲突。
全部解决。
