错误讯息：
ArgumentError: Invalid route name, already in use: 'new_user_session'
You may have defined two routes with the same name using the：为option, or you maybe overriding a route already defined by a resource with the same naming.
这是我的routes.rb
root 'static_pages#launch'

mount RailsAdmin::Engine => '/admin', :as => 'rails_admin'
mount Ckeditor::Engine => '/ckeditor'

devise_for :users , controllers: { omniauth_callbacks: "users/omniauth_callbacks"}
match '/del_google_calendar_alert', to:'set_alerts#remove_google_calendar_alert', via: 'get'
