AppComponentのサービスにInjectディレクティブを追加することで問題を解決しました

constructor(@Inject(AppService) service: AppService)

これで1日後、私は自分が必要とは思わないポリフィルをいくつか取り除いたことに気付きました。これは私が欠けていたものです：import 'core-js/es7/reflect'; 見る https://github.com/angular/angular/issues/19417#issuecomment-359722822詳細については。

App.module.shared.tsのこの行の後にセミコロンを入れてみてください。

import { AppService } from './app.service'

このエラーは、構文エラー、コンマの重複、セミコロンの欠落など、さまざまな理由で発生する可能性があります

サービスは、次のように相対パスから参照する必要があります。

必要だと思う

import { AppService } from '.app/app.service';

の代わりに

import { AppService } from '@app/app.service';

もう1つの方法は、appServiceのInjectable構成を更新することです。

@Injectable({
  providedIn: 'root'
})
export class AppService { }

または/およびAppModuleSharedで：

@NgModule({
...
})
export class AppModuleShared {
  static forRoot(): ModuleWithProviders {
    return {
      ngModule: AppModuleShared,
      providers: [AppService],
    }
  }
}

すべてのモジュールの前に、このバグimport 'core-js'を解決しました。ただし、ハイブリッドアプリがありました。

これを試してください。それは私のために機能し、ポリフィルの問題のようです。
