Question

我有一个允许我通过WebSocket连接到另一台设备的代码。它可以完美地在Ubuntu 16.04.2上运行，但是我必须在macOS High Sierra（10.13.5）上对其进行测试。

但是在macOS上有一个错误：

Traceback (most recent call last):
  File "/Users/valentindusollier/Desktop/dusollier@dfs/Home/bin/main.py", line 126, in <module>
    b.append(Accessory(a.attrib["id"], a.find("name").text, rooms.getRoomByID(a.attrib["rooms"]), a.find("image").text, a.find("address").text))
  File "/Users/valentindusollier/Desktop/dusollier@dfs/Home/bin/classes/Accessories.py", line 38, in __init__
    self.connect('ws://' + self.addr)
  File "/Users/valentindusollier/Desktop/dusollier@dfs/Home/bin/classes/Client.py", line 36, in connect
    ws_conn = websocket.WebSocketClientConnection(ioloop.IOLoop.current(), request)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/tornado/websocket.py", line 1087, in __init__
    scheme, sep, rest = request.url.partition(':')
AttributeError: 'KQueueIOLoop' object has no attribute 'url'

提示： self.connect('ws://' + self.addr)的调用值类似于ws://192.168.1.102:9001
