git push herokuが成功しない(webpack not installedが消えない)

前提・実現したいこと

Railsでwebサービスを作成しています。
git push herokuが成功しません。

webpack not installedが出ているので、指示に従ってnpm install --save-dev webpackを実行しましたが、同じエラーが出てしまい改善しません。
rails webpacker:installも試しましたがダメでした。

どうすればこのエラーを解決できるか教えていただきたいです。

程度の低い質問でしたら申し訳ございません。
また、質問に必要な情報等に不足があれば、お手数ですがご指摘いただければ、追記いたします。

よろしくお願いいたします。

エラーログを見る限り、assets:precompileのタイミングでyarnを実行しています。
おそらく、リポジトリ内にはyarn.lockが存在しており、これを認識してコマンドを実行しています。

herokuにプッシュしているリポジトリにyarn.lockがあるかを確認し、
存在するならのであればローカルでの作業として、
npm install --save-dev webpackの代わりに
yarn add -D webpackを行うことで解消する可能性があります。
