Angular8 Firebase構成エラー '@ angular / fire / angularfire2'

17

FirebaseでAngularを構成した後で「ng serve」を実行しようとすると、エラーが発生しました。このエラーメッセージをグーグルで検索しましたが、何も見つかりませんでした。エラーメッセージでは、この問題はライブラリ自体に関連しています。

一部のコンポーネントまたはサービスでのangularfire2の呼び出しなどの詳細情報を共有できますか？

@KingDarBojaありがとう！投稿を更新しましたが、angularfire2については特に言及していません。

このエラーは、AngularFireライブラリの定義ファイルをチェックするTypeScriptタイプが原因です。

エラーはからのものnode_modules/@angular/fire/angularfire2.d.ts:37:49です。

このエラーを回避するには、でいくつかのオプションを設定する必要がありますtsconfig.json。

tsconfig：

{
  //...
  compilerOptions: {
    "skipLibCheck": true,
    //...
  }
}

skipLibCheck：宣言ファイルの型チェックをスキップします。

skipLibCheckオプションの詳細。
