最近在学习django框架，教程是django入门与实践。在第14章用户注册部分，有个登录页面如下： {% extends 'base.html' %} {% load static %} {% block stylesheet %} <link rel="stylesheet" href="{% static 'css/accounts.css' %}"> {% endblock %} {% block body %} <div class="container"> <h1 class="text-center logo my-4"> Django Boards </h1> <div class="row justify-content-center"> <div class="col-lg-8 col-md-10 col-sm-12"> <div class="card"> <div class="card-body"> <h3 class="card-title">Sign up</h3> <form method="post" novalidate> {% csrf_token %} {% include 'includes/form.html' %} <button type="submit" class="btn btn-primary">Create an account</button> </form> </div> <div class="card-footer text-muted text-center"> Already have an account?Log in </div> </div> </div> </div> </div> {% endblock %} 页面可以正常加载，但是accounts.css引入失败，谷歌浏览器开发者工具查看head发现并没有实现css引入，settings已正常设置。后台提示如下： [27/Nov/2019 17:00:34] "GET /static/css/app.css HTTP/1.1" 200 55 [27/Nov/2019 17:00:34] "GET /static/css/bootstrap.min.css HTTP/1.1" 200 155758 [27/Nov/2019 17:00:36] "GET /static/css/bootstrap.min.css.map HTTP/1.1" 404 1688 求大神解释为啥css引入无效
