如何使用 popper.js 和 bootstrap 初始化工具提示

Question

我正在按照@https://getbootstrap.com/docs/4.3/components/tooltips/

的说明使用bootstrap工具提示

我已成功创建工具提示，但工具提示未格式化。我相信这是因为工具提示没有被初始化。我在页面上的不同位置添加了代码 below.Tried 初始化代码。

我可以通过在 head

中添加 bootstrap import 来解决这个问题

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="Martious">
    <link rel="shortcut icon" href="/static/favicon.ico">
    <title>Start Your Data Science Journey Here...</title>
    <!-- Bootstrap Core CSS -->
    <link href="/static/css/bootstrap.min.css" rel="stylesheet">
    <!-- Additional Custom Style CSS -->
    <link href="/static/css/starter-template.css" rel="stylesheet">
    <link href="/static/open-iconic/font/css/open-iconic-bootstrap.css" rel="stylesheet">

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>

</head>

根据 bootstrap 建议 (https://getbootstrap.com/docs/4.3/getting-started/introduction/#starter-template)，这不是，但它有效。
