Question

我正在将项目角度版本从4.4.7升级到最新版本。我将node.js更新为最新版本（8.11.1），并将angular cli更新为最新版本（1.7.4）。现在，当我使用npm start运行我的代码时，这是完整的错误。

请删除从子模块导入的角度BrowserModule，BrowserAnimationsModule / NoopAnimationsModule。并将这些导入内容包含在“父模块”中，您就很好了。

//import { BrowserModule }  from '@angular/platform-browser';
//import { BrowserAnimationsModule, NoopAnimationsModule } from '@angular/platform-browser/animations';
@NgModule({
  declarations: [..],
  imports: [
    CommonModule,
    //BrowserModule,
    //BrowserAnimationsModule,
    //NoopAnimationsModule,
  ],
  providers: [],
})
export class ChildModule { }

TypeError：无法读取null的属性'getGlobalEventTarget'
