javascript - 未捕获的类型错误 : Cannot read property 'setAttribute' of undefined at Object. onLoad

Question

任何可能导致此错误的想法？

我的包含列表:

<link rel="stylesheet" href="../../node_modules/semantic-ui/dist/semantic.min.css">
<link rel="stylesheet" href="../../node_modules/font-awesome/css/font-awesome.min.css">
<link rel="stylesheet" href="../../node_modules/bootstrap/dist/css/bootstrap.min.css">
<link rel="stylesheet" href="../../node_modules/fullcalendar/dist/fullcalendar.min.css">
<script src="../../node_modules/semantic-ui/dist/semantic.min.js"></script>
<script src="../../node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"></script>
<script src="../../node_modules/moment/min/moment.min.js"></script>
<script src="../../node_modules/fullcalendar/dist/fullcalendar.min.js"></script>

HTML 元素:

<div class="ui floating dropdown labeled search icon button" style="width: 95%; margin: 0 auto;" id="monthDrop">
    <i class="calendar icon"></i>
    <span class="text">Choose a Month</span>
    <div class="menu">
                <div class="item">January</div>
                <div class="item">February</div>
                <div class="item">March</div>
                <div class="item">April</div>
                <div class="item">May</div>
                <div class="item">June</div>
                <div class="item">July</div>
                <div class="item">August</div>
                <div class="item">September</div>
                <div class="item">October</div>
                <div class="item">November</div>
                <div class="item">December</div>
    </div>
</div>

脚本:

$('#monthDrop').dropdown();

它呈现的很好，加载时没有任何错误，只是当我尝试点击它时:

我们在使用以下 html 时遇到了同样的错误:

<select class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" role="button" v-model="selected" aria-haspopup="true" aria-expanded="false">
    <option disabled value="">Please select one</option>
    <option class="dropdown-item" value="type1">Carrier</option>
    <option class="dropdown-item" value="type2">Shipper</option>
</select>

我们尝试删除 data-toggle="dropdown"来自 <select>标签;错误不再发生，下拉菜单仍然有效。不确定为什么这行得通，但它为我们消除了错误。一定是某种冲突？无论如何，如果其他人正在寻找解决方案，此解决方法可能对他们有用。
