模板分析错误:无法绑定到'ngbTypeahead‘，因为它不是'input’的已知属性

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

@NgModule({
  imports: [
    NgbModule
  ]
})
export class AppModule { }

<input type="text" [(ngModel)]="searchTerm" [ngbTypeahead]="search">

search = (text$: Observable<string>) =>
  text$.pipe(
    debounceTime(200),
    distinctUntilChanged(),
    switchMap(term => this.getAutoCompleteResults(term))
  );

getAutoCompleteResults(term: string): Observable<string[]> {
  // 根据输入的term获取自动完成结果的逻辑
}
