我使用rails 4.2.6在我的Mac上的rails应用程序上创建了一个ruby，并在终端中键入rails server。看起来很好，直到我在Google Chrome中使用localhost：3000。
错误是：
localhost 拒绝连接
ERR_CONNECTION_REFUSED
我在终端输入rails s时得到的输出是：
=> Booting WEBrick
=> Rails 4.2.6 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

这是我的路线档案：
Rails.application.routes.draw do
get '/index' => 'welcome#index'
get '/' => 'welcome#index'
get '/welcome' => 'welcome#index'
get 'signup' => 'users#new'
resources :users
get '/learn/' => 'learn#hub'
get '/login' => 'sessions#new'
post 'login' => 'sessions#create'
get '/logout' => 'sessions#destroy'
delete 'logout' => 'sessions#destroy'
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".
# You can have the root of your site routed with "root"
# root 'welcome#index'
# Example of regular route:
# get 'products/:id' => 'catalog#view'
# Example of named route that can be invoked with purchase_url(id: product.id)
# get 'products/:id/purchase' => 'catalog#purchase', as: :purchase
# Example resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Example resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Example resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Example resource route with more complex sub-resources:
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', on: :collection
# end
# end
# Example resource route with concerns:
# concern :toggleable do
# post 'toggle'
# end
# resources :posts, concerns: :toggleable
# resources :photos, concerns: :toggleable
# Example resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
end
当我尝试rake路线时，它说：
rake aborted!
