StaticInjectionError in ng-bootstrap

Question

我需要在我的项目中实现一个评级系统，所以我尝试使用ng-bootstrap模块，并使用以下代码：

<ngb-rating [(rate)]="currentRate"></ngb-rating>

但在浏览器上运行时会出错：

ng:///AppModule/SearchResultsComponent.ngfactory.js:55 ERROR Error: StaticInjectorError[NgbRatingConfig]: 
  StaticInjectorError[NgbRatingConfig]: 
    NullInjectorError: No provider for NgbRatingConfig!

请确保您在app.module.ts中导入了**NgbModule**

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';

imports:      [ 
  NgbModule.forRoot(),
]
