ngJsTree TypeError：scope.tree.jstree不是函数

Question

我已将所需的依赖项和ngJsTree模块包含到我的app.module中。但这仍然会发生：

angular.js:13424 TypeError: scope.tree.jstree is not a function
at m.scope.destroy (ngJsTree.min.js:243)
at ngJsTree.min.js:286
at m.$digest (angular.js:16869)
at m.$apply (angular.js:17133)
at g (angular.js:11454)
at x (angular.js:11652)
at XMLHttpRequest.v.onload (angular.js:11593)

我的包括：

    <script src="js/angular.min.js"></script>
    <script src="js/angular-route.min.js"></script>
    <script src="js/lodash.js"></script>
    <script src="js/angularjs-dropdown-multiselect.js"></script>
    <script src="https://apis.google.com/js/client.js"></script>
    <script src="//cdnjs.cloudflare.com/ajax/libs/jstree/3.0.9/jstree.min.js"></script>
    <script src="js/ngJsTree.min.js"></script>
    <script src="js/app.js"></script>

我的HTML：

<div js-tree="treeConfig" ng-model="googleDriveFiles" tree-events="ready:readyCB;changed:onItemChanged"></div> 

app.js的模块部分：

var app = angular.module('app', [
    'ngRoute','ngMaterial','angularjs-dropdown-multiselect','ngJsTree'
]);
