Flask看不到静态文件

Question

问候，到现在为止我的静态文件。 我正在使用VS Code作为编辑器。 我无意中单击了调试模式，然后它停止查看我的静态文件。 我再次启动VS Code，但结果没有改变。 我怎么解决这个问题？ 当我打开localhost时，它显示127.0.0.1:5000/static/css/main.css，但是当我显示页面源代码并在新页面上打开css文件时出现错误。

我在浏览器中遇到的错误是： TypeError：make_conditional（）得到了意外的关键字参数'accept_ranges'

我在VS Code中收到的错误如下：

127.0.0.1 - - [12/Dec/2018 23:17:50] "GET /static/css/main.css HTTP/1.1" 500 -
