私は Ruby on Rails チュートリアルに取り組んでおり、第 9 章までほとんど進んでいます。何らかの理由でこれら 3 つのエラーが発生し続けているため、何か不足していないかどうかを確認するために github を確認しましたが、正確には私が持つべきもの。ここに私のエラーがあります：
1) Authentication signin with valid information followed by signout
Failure/Error: before { click_link "Sign out" }
NameError:
undefined local variable or method `sign_out' for #<SessionsController:0x104c0b9d0>
# ./app/controllers/sessions_controller.rb:19:in `destroy'
# (eval):2:in `send'
# (eval):2:in `click_link'
# ./spec/requests/authentication_pages_spec.rb:44
2) 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:65
3) Authentication authorization for non-signed-in users when attempting to visit a protected page after signing in when signing in again should render the default (profile) page
Failure/Error: click_link "Sign out"
NameError:
undefined local variable or method `sign_out' for #<SessionsController:0x104c358c0>
# ./app/controllers/sessions_controller.rb:19:in `destroy'
# (eval):2:in `send'
