Herokuへデプロイをしたいがエラーになる

Question

実現したいこと

ここに実現したいことを箇条書きで書いてください。
Herokuにデプロイしたい。

前提

ここに質問の内容を詳しく書いてください。
（例）
Heroku 18の更新の締め切りが４月末までなので、サイトで更新設定して次回デプロイしたら更新されますと書いてあったので、デプロイしたくてgit push heroku mainを入れたら何度もエラーになったので自分で色々検索したりnodeやnmpなどの設定したりしてみました。それでもエラーになったから強制的に上書きするgit push heroku main -fというコードが書いてあるサイトを見つけてやってみたのですがエラーになってしまい先に進めません。

補足情報（FW/ツールのバージョンなど）

久しぶりすぎて忘れてしまっていて初心者的でわかりづらいまとめと質問で申し訳ありません。

Answer 1

お返事遅くなり大変申し訳ございません。
お忙しい中ご返答いただきありがとうございました。
ご回答の通り、試行錯誤、四苦八苦なんとかやってみようと思います。

Answer 2

「node-sass」のコマンドが失敗しています。

ログを確認すると、以下のエラーが出ています。

error /tmp/build_cc3791e1/node_modules/node-sass: Command failed

さらにログを追っていくと、以下のエラーが出ています。

gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2

このエラーの原因は、node-sassが依存しているnode-gypがpython2を使用しているのと、
Heroku-22スタックからpython2が含まれなくなったために起きています。

node-sassは非推奨とされているため、Dart Sass（npmのパッケージ名はsass）に移行することが望ましいです。
