Python 3.x 如何解决django静态文件未找到的错误

我正在做一个项目，在这个项目中，我使用了在线网站上的前端模板。 但我认为我已经把每个文件都放在了正确的位置，但我得到的是静态文件未找到的错误。 以下是重要文件： 设置.py

我也尝试了静态文件的URL，但它不工作，请帮助我疯了

我也尝试了collectstatic，但没有发生任何情况，我不明白问题所在。请帮助

您可以尝试将css文件放置在Gym/static/Gym/下吗？将css文件放置在此处

并在index.html中使用下面的

<link rel="stylesheet" href="{% static 'Gym/bootstrap.min.css' %}" type="text/css">

<link rel="stylesheet" href="{% static 'Gym/bootstrap.min.css' %}" type="text/css">
