我需要帮助，我不能在 angular-gantt 中使用任务之间的依赖关系。我发现了这个错误：
TypeError：无法在新的 DependenciesManager （http://localhost:8080/ ....
HTML文件代码：
<div class="col-sm-12"
gantt data=gantEventsData
from-date="ganttOptions.fromDate"
to-date="ganttOptions.toDate"
view-scale="ganttOptions.scale"
headers="ganttOptions.headers"
current-date="ganttOptions.currentDate"
max-height="ganttOptions.maxHeight"
side-width = "ganttOptions.sideWidth"
allow-side-resizing="ganttOptions.allowSideResizing" >
<gantt-dependencies></gantt-dependencies>
<gantt-tree></gantt-tree>
</div>
package.json 中的依赖对象
