windows下python访问ipv6报错

错误

Traceback (most recent call last):
  File "test.py", line , in <module>
    app.run()
  File "D:\dev\Python27\lib\site-packages\web\application.py", line , in run
    return wsgi.runwsgi(self.wsgifunc(*middleware))

    server_addr = validip(listget(sys.argv, , ''))

    if validip6addr(ip): return (ip,port)
  File "D:\dev\Python27\lib\site-packages\web\net.py", line , in validip6addr
    socket.inet_pton(socket.AF_INET6, address)
AttributeError: 'module' object has no attribute 'inet_pton'

解决方法，修改D:\dev\Python27\Lib\site-packages\web\net.py

def validip6addr(address):
    """
    Returns True if `address` is a valid IPv6 address.

        >>> validip6addr('::')
        True
        >>> validip6addr('aaaa:bbbb:cccc:dddd::1')
        True
        >>> validip6addr('1:2:3:4:5:6:7:8:9:10')
        False
        >>> validip6addr('12:10')
        False

    """
    try:
        socket.inet_pton(socket.AF_INET6, address)

    return False
