Question

我遇到错误：未捕获（承诺）：错误：模板解析错误： 由于它不是'input'的已知属性，因此无法绑定到'owlDateTime'。

我已经从“ ng-pick-datetime”导入import {OwlDateTimeModule，OwlNativeDateTimeModule};在module.ts中

<div>
  <input [owlDateTime]="dt2" placeholder="Date Time" />
  <span [owlDateTimeTrigger]="dt2"><i class="fa fa-calendar"></i></span>
  <owl-date-time #dt2></owl-date-time></div>
