Question

在设置django所需的全部内容之后，我尝试了runserver命令并发现错误：

UnicodeDecodeError ：'utf-8'编解码器无法将字节0xcf解码到位 8：无效的连续字节

自：

c:\sue>python manage.py runserver
Validating models...

我使用的是Windows 7 x64，python 3.4和django 1.6.2。这个错误意味着什么？

Answer 1

这听起来像this Python issue。如果您的计算机名称具有非ASCII字符，则此操作将失败。你可以：

使用显式主机和端口发出runserver命令：python manage.py runserver 127.0.0.1:8000
将您的计算机名称更改为仅包含ASCII字符的字符串。

Answer 2

我刚遇到这个问题，因为我不小心使用https而不是http来访问该网站。切换回http修复它。

Answer 3

我在python 3.4上遇到了这个问题，情况如下：

服务器确实有一个仅支持ascii的主机名（如host1）
/ etc / hosts文件不包含主机名
没有可用的DNS解析器（离线计算机）

将以下条目添加到/etc/hosts文件后，不再引发UnicodeDecodeError个例外。

127.0.0.1 localhost host1

带有runserver的Unicodedecodeerror
