Rails教程:第3课添加静态“关于”页面

Question

我正在完成Michael的RoR教程，是"3.2.2 -添加一个页面“。

在尝试bundle exec rspec spec/requests/static_pages_spec.rb时，我会得到以下错误，即使我已经按照教程完成了所有操作(所有页面都应该就位，等等)：

以下是(据我理解)完成这项工作所需的页面，在添加这些页面之前，没有出现错误：

app/views/static_pages/about.html.erb

<h1>About Us</h1>
<p>
  The <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
  is a project to make a book and screencasts to teach web development
  with <a href="http://rubyonrails.org/">Ruby on Rails</a>. This
  is the sample application for the tutorial.
</p>

app/controller/static_pages_controller.rb

class StaticPagesController < ApplicationController

  def home
  end

  def help
  end

  def about
  end

end

config/routes.rb

SampleApp::Application.routes.draw do
  get "static_pages/home"
  get "static_pages/help"
  get "static_pages/about"
  .
  .
  .
end

spec/requests/static_pages_spec.rb

require 'spec_helper'

describe "Static pages" do

  describe "Home page" do

    it "should have the content 'Sample App'" do
      visit '/static_pages/home'
      page.should have_content('Sample App')
    end
  end

  describe "Help page" do

    it "should have the content 'Help'" do
      visit '/static_pages/help'
      page.should have_content('Help')
    end
  end

  describe "About page" do

    it "should have the content 'About Us'" do
      visit '/static_pages/about'
      page.should have_content('About Us')
    end
  end

end

从堆栈跟踪的第一行来看，它似乎显式地包含了垂直椭圆。我怀疑这篇教程作者并没有打算写“.”。包括-更多地表明在三个静态页面路由和routes.draw块结束之间可能有额外的行。
