javascript - Fullcalendar popover error : Bootstrap tooltips require Popper. js 虽然这已经包含在内

Question

我试图在我的 codeignitor 应用程序中向我的全日历添加弹出窗口，但是，尽管提到的库显然已经包含在内，但我仍然收到以下错误:Bootstrap 工具提示需要 Popper.js。

这是我的 JavaScript 库的顺序:

  <!-- JS Libs -->

    <script src="https://code.jquery.com/jquery-3.3.1.js" integrity="sha256-2Kok7MbOyxpgUVvAk/HJ2jigOSYS2auK4Pfzbm7uH60=" crossorigin="anonymous"></script
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script>

    <script type="text/javascript" src="<?php echo base_url('assets/fullcalendar-3.9.0/fullcalendar.js')?>"></script>

这是我的日历配置中的相关部分

eventRender: function(eventObj, $el) {
        $el.popover({
            title: eventObj.title,
            content: eventObj.description,
            trigger: 'hover',
            placement: 'top',
            container: 'body'
        });

您似乎忘记正确关闭您的第一个脚本。
