python - 运行服务器的 Unicodedecodeerror

Question

在设置完django 所需的所有内容后，我尝试了runserver 命令，但我发现了一个错误:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 8: invalid continuation byte

我使用的是 Windows 7 x64、python 3.4 和 django 1.6.2。这个错误是什么意思？

这听起来像 this Python issue .如果您的计算机名称包含非 ASCII 字符，这将失败。你可以:

1. 使用明确的主机和端口发出 runserver 命令:python manage.py runserver 127.0.0.1:8000
2. 将您的计算机名称更改为仅包含 ASCII 字符的字符串。
