Rake中止語法錯誤Ruby

Question

我已經開始使用http://guides.rubyonrails.org/getting_started.html學習Ruby on Rails。我絕不是編程新手，但Ruby on Rails與我以前的不同。

我在第5步，需要創建新的文章資源。當我修改配置/ routes.rb中文件看起來像這樣：

Blog2::Application.routes.draw do 
get "welcome/index" 

Blog2::Application.routes.draw do 

resources :posts 


# The priority is based upon order of creation: 
# first created -> highest priority. 

# Sample of regular route: 
# match 'products/:id' => 'catalog#view' 
# Keep in mind you can assign values other than :controller and :action 

# Sample of named route: 
# match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase 
# This route can be invoked with purchase_url(:id => product.id) 

# Sample resource route (maps HTTP verbs to controller actions automatically): 
# resources :products 

# Sample resource route with options: 
# resources :products do 
#  member do 
#  get 'short' 
#  post 'toggle' 
#  end 
# 
#  collection do 
#  get 'sold' 
#  end 
# end 

# Sample resource route with sub-resources: 
# resources :products do 
#  resources :comments, :sales 
#  resource :seller 
# end 

# Sample resource route with more complex sub-resources 
# resources :products do 
#  resources :comments 
#  resources :sales do 
#  get 'recent', :on => :collection 
#  end 
# end 

# Sample resource route within a namespace: 
# namespace :admin do 
#  # Directs /admin/products/* to Admin::ProductsController 
#  # (app/controllers/admin/products_controller.rb) 
#  resources :products 
# 

# You can have the root of your site routed with "root" 
# just remember to delete public/index.html. 
#root :to => 'articles#new' 


root :to => 'welcome#index' 

end 

我不斷收到在耙路線錯誤，它說：

rake aborted! 
SyntaxError: C:/rubygems/blog2/config/routes.rb:68: syntax error, unexpected $en 
d, expecting keyword_end 
C:in execute_if_updated' C:/rubygems/blog2/config/environment.rb:5:in' 
Tasks: TOP => routes => environment 
(See full trace by running task with --trace) 

我知道這是行68和有事用「結束」來做，但我已確定「結束」未註釋。

有誰知道這個問題是什麼？

您每次啓動塊時都會調用方法Blog2::Application.routes.draw兩次。雖然你只關閉其中一個塊。解決方法是刪除第4行routes.rb文件（Blog2::Application.routes.draw do）。
