为什么我的分页bootstrap样式不起作用

i练习"烧瓶网络开发"博客文章时，分页链接分页时，bootstrap样式不起作用。很常见。是否有必要在进口时间添加？。来人帮帮我。

这是index.html

{% extends "base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
{% import '_macros.html' as macros %}
{% block head %}

    {{ super() }}
    <script type="text/javascript">
        $('[data-spy="scroll"]').each(function () {
            var $spy = $(this).scrollspy('refresh')
        })
    </script>

看来您的班级名称中有一个错别字。

尝试<ul class="pagination">而不是<ul class="pageination">。
