龙卷风Web服务器运行Hello World时出现问题(Python 2.5，Win 7)

问题描述

我正在Windows 7(64位)上使用Python 2.5.

I am using Python 2.5 on Windows 7 (64bit).

我安装了pycurl-7.15.5.1(带有Win Binaries)和龙卷风(使用pip).

I installed pycurl-7.15.5.1 (with win binaries) and tornado (using pip).

当我运行以下hello world代码时:

When I run the following hello world code:

import tornado.ioloop
import tornado.web

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello World!")

if __name__=='__main__':
    app = tornado.web.Application([(r"/",MainHandler),])
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

我收到以下错误:-

Traceback (most recent call last):

  File "hello_tornado.py", line 11, in <module>
    application.listen(8888)
  File "c:\Python25\Lib\site-packages\tornado\web.py", line 1193, in listen
    server.listen(port, address)
  File "c:\Python25\Lib\site-packages\tornado\netutil.py", line 100, in listen
    sockets = bind_sockets(port, address=address)
  File "c:\Python25\Lib\site-packages\tornado\netutil.py", line 263, in bind_sockets
    sock.setsockopt(socket.IPPROTO_IPV6, socket.IPV6_V6ONLY, 1)
  AttributeError: 'module' object has no attribute 'IPV6_V6ONLY'

推荐答案

Tornado显然在Windows上有一些IPv6混淆.您可以通过指定要侦听的IP来修复它，如下所示:

Tornado has some IPv6 confusion on windows apparently. You can fix it by specifiyig the IP you want it to listen on like this:

application.listen(8888,'127.0.0.1')

或者也许

application.listen(8888,'0.0.0.0')
