Angular 2 产品构建错误 : ERROR in Error: Illegal state: Could not load the summary for directive

Question

我在我的项目中使用 angular 2，当我使用 ng build 和 ng serve 时，我没有收到以下错误。这仅在使用 prod build ng build --prod

时发生

ERROR in Error: Illegal state:
      Could not load the summary for directive "component name"

我的项目中使用了以下依赖项。

任何人请尝试帮助解决这个问题:

Globalconstantpopup 文件声明和导入:

import { NgbModal, NgbActiveModal, ModalDismissReasons } from '@ng-bootstrap/ng-bootstrap';
import { GlobalConstantsService } from '../global-constants/global-constants.service';

@Component({
  selector: 'app-global-constants-popup',
  templateUrl: './global-constants-popup.component.html',
  styleUrls: ['./global-constants-popup.component.css'],
  providers: [GlobalConstantsService],
})
@NgModule({
  imports: [
    InlineEditorModule,

  ]
})
export class GlobalConstantsPopupComponent implements OnInit {

}

Answer 1

问题是因为您的组件上有一个 @NgModule 注释。这是不支持的(如 here 所示)

尝试从您的组件中删除这些行

@NgModule({
  imports: [
    InlineEditorModule,

 ]
})

并改为从 AppModule 导入 InlineEditorModule

我认为这在开发模式下有效，但在使用 --prod 标志构建时不起作用的原因是生产构建做了一些代码优化(angular.json 中的 >buildOptimizer 参数)，这可能会去除您的 Component 注释。
