嗨，我是 Rails 的新手。Ruby on Rails 教程第 9 章，Rspec 失败。轨道版本。是 3.2.6。这个来源是github。我有 3 次失败的测试来完成本章。

终端返回：

  $ bundle exec rspec spec/requests/user_pages_spec.rb
    ......F.FF.................

Failures:

  1) User pages index pagination should list each user
     Failure/Error: page.should have_selector('li', text: user.name)
       expected css "li" with text "Person 41" to return something

     # ./spec/requests/user_pages_spec.rb:43:in `each'
     # ./spec/requests/user_pages_spec.rb:43:in `block (4 levels) in <top (required)>'

  2) User pages delete links as an admin user 
     Failure/Error: it { should have_link('delete', href: user_path(User.first)) }
       expected link "delete" to return something
     # ./spec/requests/user_pages_spec.rb:61:in `block (4 levels) in <top (required)>'

  3) User pages delete links as an admin user should be able to delete another user
     Failure/Error: expect { click_link('delete') }.to change(User, :count).by(-1)
     Capybara::ElementNotFound:
