我想在龙卷风中运行一个 Hello World 程序
我正在使用带有 pydev 插件的 Eclipse(Ubuntu 11.10)在他们的网站(http://www.tornadoweb.org/)中在龙卷风网络服务器中运行 Hello world 程序
import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
def get(self):
self.write("Hello, world")
application = tornado.web.Application([
(r"/", MainHandler),
])
if __name__ == "__main__":
application.listen(8888)
tornado.ioloop.IOLoop.instance().start()
但是出现以下错误
Traceback (most recent call last):
File "/home/unais/workspace/Turnado/HelloWorld.py", line 13, in <module>
application.listen(8888,'0.0.0.0')
File "/usr/local/lib/python2.7/dist-packages/tornado-2.4.1-py2.7.egg/tornado/web.py", line 1289, in listen
server.listen(port, address)
File "/usr/local/lib/python2.7/dist-packages/tornado-2.4.1-py2.7.egg/tornado/netutil.py", line 120, in listen
sockets = bind_sockets(port, address=address)
File "/usr/local/lib/python2.7/dist-packages/tornado-2.4.1-py2.7.egg/tornado/netutil.py", line 286, in bind_sockets
sock.bind(sockaddr)
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 98] Address already in use
可能是什么问题?
