如何解决GET 404无法在Flask Bootstrap中加载资源错误
在我的烧瓶应用程序中加载时，出现内部服务器404 GET错误。它声称丢失的文件正是未列出的文件。
127.0.0.1 - - [06/Sep/2020 08:05:28] "GET /static/bootstrap/js/bootstrap.bundle.min.js HTTP/1.1" 404 -
127.0.0.1 - - [06/Sep/2020 08:05:28] "GET /static/bootstrap/css/bootstrap.min.css.map HTTP/1.1" 404 -
127.0.0.1 - - [06/Sep/2020 08:05:28] "GET /static/bootstrap/js/bootstrap.bundle.min.js HTTP/1.1" 404 -
我在app.py的末尾有我的app.run（），所以不是那样。
我正在使用主要的引导程序模板HTML文件，所有其他HTML文件都从该文件扩展而来。这是我的代码加载“缺少js文件”的唯一位置。这是（base.html）：
<!DOCTYPE html>
<html lang="en">
<head>

这是我的app.py文件：

对于可能出现的问题，我已经没有足够的想法了，希望我能在这里为我提供帮助。
谢谢，祝你有美好的一天。
