获取静态注入错误&；Angular7生产构建中的NullInjectorError

嗨，我正在用Angular 7开发一个Angular Progressive Web应用程序（PWA）。使用

ng build--prod执行生产构建后，我在运行时遇到以下错误：

ERROR Error: StaticInjectorError[e -> function(){}]: 
  StaticInjectorError(Platform: core)[e -> function(){}]: 
    NullInjectorError: No provider for function(){}!
    at e.get (main.c61af9b8ddfa2457805d.js:1)
    at main.c61af9b8ddfa2457805d.js:1

    at main.c61af9b8ddfa2457805d.js:1
    at Iv (main.c61af9b8ddfa2457805d.js:1)

我无法追踪错误的实际原因或可能的原因。请帮忙解决它

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { ReactiveFormsModule } from '@angular/forms';
import { StorageServiceModule } from 'angular-webstorage-service';
// Custom modules
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { ServiceWorkerModule } from '@angular/service-worker';
import { environment } from '../environments/environment';
import { LoggerService } from './common/services/logger.service';
import { Logger } from 'angular2-logger/core';
import { LoginComponent } from './components/login/login.component';
import { DashboardComponent } from './components/dashboard/dashboard.component';
import { NotfoundComponent } from './components/notfound/notfound.component';
import { FalDriverService } from './common/services/faldriver.service';
import { ApplicationSession } from './common/entities/application/application.session';
import { GlobalService } from './common/services/global.service';
import { SeedDataService } from './common/services/seeddata.service';
import { HeaderComponent } from './components/header/header.component';
import { HttpClientModule } from '@angular/common/http';
import { LoginGuardService } from './common/services/loginguard.service';
import { AppCacheService } from './common/services/appcache.service';
import { HttpService } from './common/services/http.service';
import { DatabaseService } from './common/services/database.service';

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent,
    DashboardComponent,
    NotfoundComponent,
    HeaderComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    ReactiveFormsModule,
    HttpClientModule,
    StorageServiceModule,
    ServiceWorkerModule.register('ngsw-worker.js', { enabled: environment.production })
  ],
  providers: [

  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

早些时候，我所有的服务都在提供商内部。我按照这个特定的答案删除了它们：
尝试添加这一行

environment.production ? ServiceWorkerModule.register('/ngsw-worker.js') : [],
ServiceWorkerModule.register('/ngsw-worker.js', { enabled: environment.production }),

我也有这个问题，但有8个

您可以通过运行
ng serve——在您的开发机器上本地prod
。
然后您将能够看到完整的错误消息。
dev build工作正常。仅在prod buildpost发布您的app.module.tsapp.module.ts后发布。请在导入中签入app.module.ts，对吗？我做了，但还是不起作用。我也犯了同样的错误，问题解决了。我首先使用了ng serve--aot来缩小导致问题的导入范围，并修复了它。非常感谢：）我也遇到了同样的问题，但使用了
ng serve--prod
（在Angular 8上）来解决它。
