Rails4新手:路由错误-

我对铁路很陌生。不知道如何修复。我甚至无法启动一个简单的rails应用程序!

Environment:
    Windows 7
    Ruby 2.1.0
    Rails 4.2.3

首先:我运行了generate命令

D: \railprojects\blog>rails生成控制器Pages索引

路由.rb

    Rails.application.routes.draw do
  get 'pages/index'

end

页面_控制器.rb

class PagesController < ApplicationController
  def index
  end
end

索引html.erb

<h1>Pages#index</h1>
<p>Find me in app/views/pages/index.html.erb</p>

我遇到以下错误。

http://127.0.0.1:3000/pages
