无法获取ZeroMQ python绑定以通过IPC接收消息

我正在尝试通过IPC实现PUB/SUB.如果我更改了下面的代码，以使订阅者绑定到"tcp://*:5000"，而发布者连接到"tcp://localhost:5000"，则它可以工作，但是我无法使其在IPC上工作.我在做什么错了?

I'm trying to achieve PUB/SUB over IPC. If I changed the code below so that the subscriber binds to "tcp://*:5000" and the publisher connects to "tcp://localhost:5000" it works, but I can't get it to work over IPC. What am I doing wrong?

subscriber.py

subscriber.py

import zmq, json

def main():
    context = zmq.Context()
    subscriber = context.socket(zmq.SUB)
    subscriber.bind("ipc://test")
    subscriber.setsockopt(zmq.SUBSCRIBE, '')
    while True:
        print subscriber.recv()

if __name__ == "__main__":
    main()

publisher.py

publisher.py

import zmq, json, time

def main():
    context = zmq.Context()
    publisher = context.socket(zmq.PUB)
    publisher.connect("ipc://test")
    while True:
        publisher.send( "hello world" )
        time.sleep( 1 )

if __name__ == "__main__":
    main()
