Michael Hartl Ruby on Rails tuttorial chapter9 Rspec失敗

Question

嗨，我是Rails的新手。 Ruby on Rails Tutorial第9章，Rspec faild。鐵軌版本是3.2.6。該來源是github。我有3次失敗的測試來完成本章。

終端返回此：

$ 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:44:in `block (5 levels) in <top (required)>' 
    # ./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: 
     no link with title, id or text 'delete' found 
    # (eval):2:in `click_link' 
    # ./spec/requests/user_pages_spec.rb:63:in `block (5 levels) in <top (required)>' 
    # ./spec/requests/user_pages_spec.rb:63:in `block (4 levels) in <top (required)>'
