Angularコンパイラが検出されましたが、間違ったクラスのインスタンスでした

私はこれがすでに尋ねられている質問であることを知っています私はそこで見つけたすべての可能なことを試しました。それでもそれをクラックすることはできません。どんな助けでも大歓迎です。

私は次のような考えをすべて試しました

  • Node_moduleフォルダーとPackage.lock.jsonを削除します
  • Npmの再インストール-npmインストール
  • Npmの更新を試しました

足りないものについてのここでの助けは、ここで立ち往生していることを大いに感謝します。

しかし、それでももう1つ問題があります。

ERROR in No NgModule metadata found for 'AppModule'.

誰でもここで助けてくれませんか。どんな助けでも大いに活用されます

私は同じ問題を抱えていて、次の方法で解決しました：

1）パッケージ@ngtools/webpackを最新バージョンに更新する

2）node_modules、package-lock.jsonを削除し、クリーンなnpm installを実行します

これは最良の解決策のようで、私にとっては2回機能しました。次のコマンドを実行します-

npm重複排除

監査の詳細を確認できます。修正するには、実行するだけです-

npm監査の修正

必要に応じて（エラーが続く）、次のように実行します-

npm監査修正--force

これにより、重複するすべてのパッケージが重複排除され、バージョン番号も修正されます。

お役に立てれば！

@ngtools\webpackフォルダーとpackage-lock.jsonを削除してから、yarn（notnpm installまたはnpm update）を実行します。これが良い修正かどうかはわかりませんが、うまくいきました。

プロジェクトの依存関係が競合している可能性があります。例：@angular/compiler-cliバージョンは6.1.0ですが、@angular/coreのバージョンはまだ5.20です。ダウングレードしてみてください@angular/compiler-cliから5.xにアップグレードするか、angular 6（ https://update.angular.io/ ）にアップグレードします
