我对编程很陌生，我正在尝试阅读本教程。除了为本章末尾的练习编写自己的代码外，我都遵循了给出的代码。我现在陷入了这个错误。
Failures:
1) Authentication authorization for non-signed-in users when attempting to visit a protected page after signing in should render the desired protected page
Failure/Error: page.should have_selector('title', text: 'Edit user')
expected css "title" with text "Edit user" to return something
# ./spec/requests/authentication_pages_spec.rb:63:in `block (6 levels) in <top (required)>'
Finished in 3.12 seconds
73 examples, 1 failure
Failed examples:
rspec ./spec/requests/authentication_pages_spec.rb:62 # Authentication authorization for non-signed-in users when attempting to visit a protected page after signing in should render the desired protected page
这是我添加的代码。
