如何使Timepicker出现在Angular的Dropdown中？

Question

在Bootstrap 4 docs上，您可以有一个仅包含时间选择器的可切换下拉列表。但是，我想使用一个Angular模块作为时间选择器来添加它，而不是使用香草引导程序。您可以使用NgbDatepicker完成类似的操作，但是，没有列出使用时间选择器完成此操作的示例。

我确实尝试仅使用相同的代码并将NgbDatePicker的提及更改为NgbTimePicker，但无济于事。下面的示例产生一个Template parse errors:，其中ngbTimepicker不被识别为指令。

<div class="input-group">
    <input class="form-control" name="startTime" [(ngModel)]="newEmployeeTime.StartTime" ngbTimepicker 
         #start="ngbTimepicker" [readonly]="true">

    <div class="input-group-append">
        <button class="btn btn-outline-secondary calendar" (click)="startTime.toggle()" type="button"><i 
            class="fa fa-clock"></i></button>
    </div>
</div>

当然，必须有一种不复杂的方法来完成此操作，但是我现在似乎还无法想到它。
