Question

我正在尝试在服务器上运行新创建的环境并获取UnicodeDecodeError。

Windows 7，64位。我创建了一个虚拟环境并将代码定向到源文件夹。这里是安装的django，python和virtualenv版本。我尝试安装django和python的旧版本，并得到了相同的错误。

搜索故障排除建议时，我只会找到与.csv和熊猫相关的文章。

Django==2.2.7
pytz==2019.3
virtualenv==16.7.7
PS: C:\Users\User\Dev\Selectia\src> python manage.py runserver

以下是输出：

UnicodeDecoderError: 'utf-8' code can't decode byte 0xcf in position 5: invalid continuation byte

能否请我帮忙找出解决此错误消息的方法？

P.S。这是我的第一个Web框架项目，我对python有一定的了解。我将非常感谢您提供的任何帮助。我想建立自己的网站。

您的主机文件中有别名，其中包含无法解码为UTF-8的字符。删除它们可以解决问题（将所有别名设置为仅ASCII可能是最容易的）。

Windows 7上主机文件的默认位置是

 C:\Windows\System32\Drivers\etc\hosts

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