有人可以帮我解决这个错误吗?

import pygeoip  
gi = pygeoip.GeoIP('GeoIP.dat')  
print gi.country_code_by_name('specificdownload.com')  

Traceback (most recent call last):  
  File "<module1>", line 14, in <module>  
  File "build\bdist.win-amd64\egg\pygeoip\__init__.py", line 447, in country_code_by_name  
    addr = self._gethostbyname(hostname)  
  File "build\bdist.win-amd64\egg\pygeoip\__init__.py", line 392, in _gethostbyname  
    return socket.gethostbyname(hostname)  
gaierror: [Errno 11001] getaddrinfo failed

好吧,让我们问Python是什么类型的异常:

#!/usr/bin/env python2.7

import pygeoip
gi = pygeoip.GeoIP('GeoIP.dat')
try:
    print gi.country_code_by_name('specificdownload.com')
except Exception, e:
    print type(e)
    print e

打印:

$ ./foo.py
<class 'socket.gaierror'>
[Errno 8] nodename nor servname provided, or not known

所以我们需要抓住socket.gaierror,如下:

#!/usr/bin/env python2.7

import pygeoip
import socket
gi = pygeoip.GeoIP('GeoIP.dat')
try:
    print gi.country_code_by_name('specificdownload.com')
except socket.gaierror:
    print 'ignoring failed address lookup'

虽然仍有问题,但是gaierror到底是什么?谷歌出现了the socket.gaierror documentation,其中说,

  

针对getaddrinfo()getnameinfo()

的地址相关错误,引发了此异常

因此GAI错误=获取地址信息错误。
