问题描述

我正在用Python 3.4.1来构建一个Django项目。

 manage.py runserver 引发UnicodeDecodeException。

如何解决?

查看以下(修剪)追溯:

追溯(最近的最后一次呼叫):

文件C:\ Python34\lib\socketserver.py,第429行__init__  self.server_bind()

文件C:\Python34\lib\site-packages\django\core \servers\basehttp.py,第121行,在server_bind 超级(WSGIServer,self).server_bind()

文件C:\Python34\lib\wsgiref \simple_server.py,第50行,server_bind  HTTPServer.server_bind(self)

文件C:\Python34\lib\http\server.py,第135行, server_bind  self.server_name = socket.getfqdn(host)

文件C:\Python34\lib\socket.py,第460行,getfqdn 主机名,别名,ipaddrs = gethostbyaddr(name)

UnicodeDecodeError:'utf-8'编解码器无法解码位置12中的0xcf字节无效连续字节 

每个请求,我的主机名:

 C:\Users\AnatoliyVik>主机名 AnatoliyVik-ПК 

解决方案

将主机名更改为不再包含西里尔字符解决问题。

感谢@拉法达的指导。

I'm trying to build a Django project with Python 3.4.1. manage.py runserver raises a UnicodeDecodeException.

How can this be resolved? See the below (trimmed) traceback:

Traceback (most recent call last):
  File "C:\Python34\lib\socketserver.py", line 429, in __init__
    self.server_bind()
  File "C:\Python34\lib\site-packages\django\core\servers\basehttp.py", line 121
, in server_bind
    super(WSGIServer, self).server_bind()
  File "C:\Python34\lib\wsgiref\simple_server.py", line 50, in server_bind
    HTTPServer.server_bind(self)
  File "C:\Python34\lib\http\server.py", line 135, in server_bind
    self.server_name = socket.getfqdn(host)
  File "C:\Python34\lib\socket.py", line 460, in getfqdn
    hostname, aliases, ipaddrs = gethostbyaddr(name)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 12: invalid
 continuation byte

Per request, my hostname:

C:\Users\AnatoliyVik>hostname
AnatoliyVik-ПК

Changing the hostname to no longer include Cyrillic symbols resolves the problem.

Thanks to @Lafada for the guidance.
