Angularjs ui.bootstrap指令总是出现multidir错误

当我尝试使用ui.bootstrap的指令，如$modal和$datepicker时，会出现这个错误

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）

我没有在一个标记中使用相同的命名（'datepickerPopup'）多个指令。

我猜您已经包含了两次库，因此出现了错误。给我们看更多的代码。

<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>
