当我尝试使用ui.bootstrap的指令（如$ modal和$ datepicker）时出现此错误。
Error: [$compile:multidir] Multiple directives [datepickerPopup, datepickerPopup] asking for new/isolated scope on: <input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="dt" is-open="opened" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" date-disabled="disabled(date, mode)" ng-required="true" close-text="Close">

这是我的代码（html）。
<input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="dt" is-open="opened" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" date-disabled="disabled(date, mode)" ng-required="true" close-text="Close" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
我没有在一个标签中使用相同的命名（'datepickerPopup'）多个指令。
