ngZorro-StaticInjectorError（AppModule）[Overlay]

Question

我在我的项目中使用ng-zorro，在--prod之后出现以下错误。通常情况下，服务器不会产生此错误。我发现了这个git posthttps://github.com/NG-ZORRO/ng-zorro-antd/issues/3713#issuecomment-513933229但没有为我解决。

main-es2015.fa929b87a49d088ae223.js:36985 ERROR NullInjectorError: StaticInjectorError(AppModule)[Overlay]: 
  StaticInjectorError(Platform: core)[Overlay]: 
    NullInjectorError: No provider for Overlay!

在app.module.ts中导入该项目可在ng服务器上正常工作。

@NgModule({
  declarations: [
    AppComponent,
    CommentsComponent,
  ],
  imports: [
    FlexLayoutModule,
    BrowserModule,
    AppRoutingModule,
    FormsModule,
    ReactiveFormsModule,
    HttpClientModule,
    BrowserAnimationsModule,
    NgZorroAntdModule
  ],
  providers: [
    GlobalService,
    RouteGuardService,
    { provide: HTTP_INTERCEPTORS, useClass: HttpAuthInterceptor, multi: true },
    { provide: NZ_I18N, useValue: en_US }],
  bootstrap: [AppComponent]
})
export class AppModule { }
