angular2 - DatepickerConfig 没有服务提供商

Question

我正在实现 ng2-bootstrap datepicker，但出现以下错误。请帮我解决这个问题。

EXCEPTION: Uncaught (in promise): Error: Error in
         http://localhost:8888/app/components/report.component.html:3:0 caused by: No provider for DatepickerConfig! 

module.ts

 import { DatepickerModule } from 'ng2-bootstrap';

  @NgModule({
   imports: [DatepickerModule],
   declarations: [],
   providers: [],
   bootstrap: [AppComponent]
})

组件.ts

@Component({
 module: module.id,
 selector:'my-date',
 template: `
  <h4>My Date Picker</h4>
  <datepicker></datepicker>`
})

 export class MyComponent {
 }

systemjs.config.js

System.config({ map: { 'ng2-bootstrap':
 'npm:ng2-bootstrap/bundles/ng2-bootstrap.umd.js'} })

您应该使用 forRoot()，因为它在示例存储库中是这样定义的。

  @NgModule({
   imports: [DatepickerModule.forRoot()],
   declarations: [],
   providers: [],
   bootstrap: [AppComponent]
})

By convention, the forRoot static method both provides and configures services at the same time. It takes a service configuration object and returns a ModuleWithProviders which is a simple object with two properties:

• ngModule - the CoreModule class

• providers - the configured providers

The root AppModule imports the CoreModule and adds the providers to the AppModule providers.
