angular 2アプリにng2-bootstrap datePickerを実装していますが、ある種のモジュールエラーに直面し、背後にある問題がわかりません.助けてください.

module.ts

import { DatepickerModule } from 'ng2-bootstrap/datepicker';
@NgModule({
 imports: [
 ...........  
 DatepickerModule
 ...........
 ],
 declarations: [
 .....
 .....
]})

export class Modules {
 }

html

<datepicker></datepicker>

 'datepicker' is not a known element:
    1. If 'datepicker' is an Angular component, then verify that it is part of this module.
    2. If 'datepicker' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schema' of this component to suppress this message. ("<div class="form-group"><div>
                          [ERROR ->]<datepicker></datepicker>
                          <!--<datepicker [expanded]="true" class="danger"-"): AddCustomer@49:26
    Can't bind to 'expanded' since it isn't a known property of 'datepicker'. ("                              <div>
                                                    <datepicker [ERROR ->][expanded]="true" class="danger"
                                                                form"): AddCustomer@212:64
