前提・実現したいこと

rails testを正常に動作させたいです。
rails tutorialの第3章に従いリスト３.１５まで実行しました。引数が一致しておらず、node_filter.rbの９行目からがエラー元であると解釈しています。

Capybaraはバージョン3.31.0でRuby 2.7対応が入っていますが、この修正がない場合にはRuby 2.7時点では警告のみのところ、Ruby 3.0では動かなくなります。

つまり、現在のcapybara-3.28.0は、Ruby 3.0で使うには古すぎます。

Capybaraを最新版まで上げるか、Rubyのバージョンをチュートリアルが前提としているところまで下げるかで対応してください。

ありがとうございます。教えて頂いた通り、rubyのバージョンを前提としているところまで下げたところ問題の箇所はエラーがなくなりました。ただし、付随してSQLiteが古いとのエラーが出てしまったので一度バージョン関係を最初から見直してみたいと思います。しばらく進んでいなかったので大変助かりました。ありがとうございました。
