現在、Webpack 1 から 2 へのアップグレード、そして 3 へのアップグレードに取り組んでいます。このアップグレードでは、1 => 2および2 => 3の手順に従って、移行手順に従いました。

私が抱えている問題は、インストールされているパッケージのどれもnode_modules、コード内のコード内で解決されていないように見えることですclient/app/bundles。すべての node_modules で発生するエラーは、次の構造にあります。

./node_modules/alt/lib/store/StoreMixin.js のエラー || モジュールが見つかりません: エラー: 「client/node_modules/alt/lib/store」の「送信機」を解決できません

私の理論ではfile-loader、適切expose-loaderimports-loaderバージョンがないとモジュールがインポートされないことは理にかなっているからです。パターンmodule.rulesで終わるすべてのローダーがあることを確認しました。もエラーなしで成功します。-loaderyarn install

私の依存関係と Webpack の構成は次のとおりです。
