关于angular:找不到DialogNamePromptComponent的组件工厂。您是否将其添加到@ NgModule.entryComponents?

No component factory found for DialogNamePromptComponent. Did you add it to @NgModule.entryComponents?

    import { BarChartCardComponent } from './bar-chart-card/bar-chart-card.component';
    import { DialogNamePromptComponent } from './bar-chart-card/detail-view.component';

    @NgModule({
      imports: [
        ThemeModule,
        ChartModule,
        NgxEchartsModule,
        NgxChartsModule,
        LeafletModule,
      ],
      declarations: [
    DialogNamePromptComponent,
    BarChartCardComponent
  ],
  providers: [
    CountryOrdersMapService,
  ],
  entryComponents: [BarChartCardComponent,DialogNamePromptComponent]
})
export class ECommerceModule { }

在这里,当我调用方法open3时,出现此错误:

No component factory found for DialogNamePromptComponent. Did you add it to @NgModule.entryComponents?


通常,您需要将将动态构造的任何组件添加到模块定义中的entryComponents数组中。

@NgModule({
    providers: [...],
    declarations: [...],
    entryComponents: [DialogNamePromptComponent, ... ],
    ...
})
export class YourModule { }

这在Nebular的文档中没有指定,但是我认为他们使用的是Angular的ComponentFactoryResolver,如果没有在其他地方加载该组件,则需要此。

但是,我注意到您为BarChartCardComponent类的组件装饰器错误地添加了NgModule装饰器,这是我以前从未见过的。据我所知,一个类不能同时是一个组件和一个模块。因此,删除该NgModule装饰器。


将DialogNamePromptComponent添加到父模块的entryComponents
