チュートリアルを進めていたところ、このエラーが発生しました
Failures:
1) Authentication signin followed by signout
Failure/Error: before { click_link "Sign out" }
Capybara::ElementNotFound:
no link with title, id or text 'Sign out' found
# (eval):2:in `click_link'
# ./spec/requests/authentication_pages_spec.rb:48:in `block (4 levels) in <top (required)>'
この質問を徹底的に調査しました。同様の質問がありますが、解決策を試しましたが、うまくいきませんでした。

編集。
カピバラのエラーはなくなりましたが、新しいエラーが発生しました。
失敗:

ここで何が問題なのですか？私の構文は正しく、その行は以前はエラーを出していなかったのに、なぜ今なのか? なぜこれが起こっているのか、助けと説明をいただければ幸いです。
