###### **无法显示bootstrap样式，bootstrap已成功存放在项目目录中**

引入放到上面试一下

你是不是忘记写{% load static %}啦？写在html最前面就行啦。
然后还有就是你引入jquery的时候，你自己跟你自己的文件系统结构对一下，可能是放在 js/jquery-3.6.1.min.js
然后还有版本号记得对
然后检查文件名字有没有写错
如果还有问题，把你的文件系统结构截个图我看看

我的文件结构是这样，所以我是这样引入的

<link rel="stylesheet" href="{% static '/plugins/bootstrap-3.4.1/css/bootstrap.min.css' %}">

<script src="{% static 'js/jquery-3.6.3.min.js' %}" ></script>
<script srt="{% static 'plugins/bootstrap-3.4.1/js/bootstrap.min.js' %}"></script>

实在不行你就引cdn在线的吧

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">

<script src="https://cdn.jsdelivr.net/npm/jquery@1.12.4/dist/jquery.min.js" ></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>

实在不行只能这样啦
