日历弹出窗口无效

Question

当我使用angular.module("task", ['angularSpinner','ui.bootstrap'])时，日历弹出窗口无法正常工作。我收到了错误：

  

错误：指令datepickerPopup：=？

的隔离范围定义无效

这是我的HTML页面

<div class="modal fade" id="myModal" tabindex="-1" data-backdrop="static" data-keyboard="false">

                    </div>
                </div>

这是我的控制器

$scope.today = function() {
    $scope.dt = new Date();
  };
  $scope.today();

  $scope.clear = function () {
    $scope.dt = null;
  };

  // Disable weekend selection
  $scope.disabled = function(date, mode) {
    return ( mode === 'day' && ( date.getDay() === 0 || date.getDay() === 6 ) );
  };

  $scope.toggleMin = function() {
    $scope.minDate = $scope.minDate ? null : new Date();
  };
  $scope.toggleMin();

  $scope.open = function($event) {
    $event.preventDefault();
    $event.stopPropagation();

    $scope.opened = true;
  };

  $scope.dateOptions = {
    formatYear: 'yy',
    startingDay: 1
  };
