Question

我正在关注Michael Hartl的Ruby on Rails教程，当我运行时，我在3.2.1节中遇到以下错误：

bundle exec rspec spec/requests/static_pages_spec.rb

我看到过类似的错误，但没有完全相同。任何援助将不胜感激。

错误：

尝试将 static_pages_spec.rb 文件设置为：

require 'spec_helper'

describe "Static pages" do

  describe "Home page" do

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

    it "should have the base title" do
      visit '/static_pages/home'
      expect(page).to have_title("Ruby on Rails Tutorial Sample App")
    end

    it "should not have a custom page title" do
      visit '/static_pages/home'
      expect(page).not_to have_title('| Home')
    end
  end
end
