当我安装ActiveAdmin(对于现有模型用户)时,此链接停止工作：

undefined local variable or method `new_user_registration_path'

我使用git diff作为routes.rb,这里是(添加的行是黑色的)：

ActiveAdmin.routes(个体经营)
devise_for：users,ActiveAdmin :: Devise.config

另外<％= link_to“退出”,destroy_user_session_path,：method => ：删除％>现在导致/ admin / logout

我怎么解决这个问题？

耙路线：

admin_dashboard            /admin(.:format)                       {:action=>"index",:controller=>"admin/dashboard"}

我检查了旧版本,路线是：

            user_session POST   /users/sign_in(.:format)               {:action=>"create",:controller=>"devise/sessions"}
    destroy_user_session DELETE /users/sign_out(.:format)              {:action=>"destroy",:controller=>"devise/sessions"}
           user_password POST   /users/password(.:format)              {:action=>"create",:controller=>"devise/passwords"}
       new_user_password GET    /users/password/new(.:format)          {:action=>"new",:controller=>"devise/passwords"}
      edit_user_password GET    /users/password/edit(.:format)         {:action=>"edit",:controller=>"devise/passwords"}
                         PUT    /users/password(.:format)              {:action=>"update",:controller=>"devise/passwords"}
cancel_user_registration GET    /users/cancel(.:format)                {:action=>"cancel",:controller=>"devise/registrations"}
       user_registration POST   /users(.:format)                       {:action=>"create",:controller=>"devise/registrations"}
