如何找到包含錯誤的文件？

hy。我剛剛將我的應用程序更新爲角度4.4.3和最新的角度材質。之後萬噸的錯誤，現在我只有一次，但看起來有點混亂，因爲這是很難理解什麼是文件錯誤的名稱在我得到錯誤：如何找到包含錯誤的文件？

你能幫助我嗎？錯誤在哪裏？我認爲錯誤是在文件main.ts，但是隻有短短的幾行：

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; 
import { AppModule } from './app/app.module'; 
platformBrowserDynamic().bootstrapModule(AppModule);

有在AppModule只有一個地方可以與providers有關：

//changes languages that are set locally 
import { TranslateModule, TranslateLoader } from '@ngx-translate/core'; 


@NgModule({ 
    imports: [..., 

TranslateModule.forRoot({ 

      loader: { 
       provide: TranslateLoader, 
       useFactory: HttpLoaderFactory, 
       deps: [Http] 
      } 

     })

而且，還有其他地方在路由的其他組件文件中：

//used for listing json as treeview 
import { 
    TreeviewI18n, 
    TreeviewItem, TreeviewConfig, 
    TreeviewHelper, 
    TreeviewComponent, 
    TreeviewEventParser, OrderDownlineTreeviewEventParser, 
    DownlineTreeviewItem 
} from 'ngx-treeview'; 


@Component({ 

    selector: '...', 

    templateUrl: '...', 

    providers: [HttpService, 
     { provide: TreeviewEventParser, useClass: OrderDownlineTreeviewEventParser } 
    ] 


})

您遇到了無效提供程序的問題，此對象需要[對象對象]。但是添加你的代碼，因爲這不是一個答案，它只是調試錯誤所說的。 – 2017-10-09 07:55:48

問題出在你的AppModule裏面，你在你的AppModules提供者數組中添加了一個錯誤的東西。發佈你的'AppModule'的代碼 – PierreDuc

@PierreDuc你能看到我更新的帖子嗎？ – AmoT

檢查模塊中的提供程序 - 您可能傳遞對象而不是提供程序類。
