突然,当我尝试打开下拉菜单时,我开始出错:

 bootstrap.min.js:6 Uncaught Error: Bootstrap dropdown require Popper.js (https://popper.js.org)
        at bootstrap.min.js:6
        at bootstrap.min.js:6
        at bootstrap.min.js:6

我正在使用标准的bootstrap文件

<script src="https://getbootstrap.com/dist/js/bootstrap.min.js">

引导程序有什么变化我必须要小心吗？

订单我正在加载文件如下

<script src="https://code.jquery.com/jquery-1.9.1.js"></script>
<script src="{{ STATIC_URL }}/static/jquery/jquery-1.9.1.js"></script>
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<script src="{{ STATIC_URL }}/static/jquery/jquery-ui.js"></script>
