如何修复 UnicodeDecodeError：'utf-8'编解码器无法解码位置 5 中的字节0xcf：无效的延续字节

Question

我正试图在服务器上运行一个新创建的环境，并获取UnicodeDecodeError。

Windows 7，64位。我已经创建了一个虚拟环境，并将代码定向到源文件夹。以下是安装的django、python和virtualenv版本。我试过安装django和python的旧版本，但也出现了同样的错误。

在搜索故障排除建议时，我只找到与.csv和panda相关的文章。

Django==2.2.7
pytz==2019.3
virtualenv==16.7.7
PS: C:UsersUserDevSelectiasrc> python manage.py runserver

这是输出：

你能帮我找出如何处理这个错误消息的方法吗？

第页。S.这是我的第一个web框架项目，我对python有一些了解。如果能提供任何帮助，我将不胜感激。我想建立自己的网站。
