python-3.x - 导入错误: cannot import name 'create_connection'

Question

我正在使用 Python 3.4 和 websocket-client 0.44。我正在尝试使用 Python webscoket 脚本从 Bitfinex 获取流数据使用套接字。这是我编写的脚本:

import json

from websocket import create_connection

ws = create_connection("wss://api.bitfinex.com/ws/2")
#ws.connect("wss://api2.bitfinex.com:3000/ws")
ws.send(json.dumps({
    "event": "subscribe",
    "channel": "book",
    "symbol": "tBTCUSD",
}))


while True:
    result = ws.recv()
    result = json.loads(result)
    xxx = result
    print(xxx)
    #print(result[1])

ws.close()

我得到的是错误:

Traceback (most recent call last):
  File "D:/bitstamp/socket.py", line 3, in <module>
    from websocket import create_connection
  File "C:\Python34\lib\site-packages\websocket_client-0.44.0-py3.4.egg\websocket\__init__.py", line 23, in <module>
    from ._app import WebSocketApp
  File "C:\Python34\lib\site-packages\websocket_client-0.44.0-py3.4.egg\websocket\_app.py", line 35, in <module>
    from ._core import WebSocket, getdefaulttimeout
  File "C:\Python34\lib\site-packages\websocket_client-0.44.0-py3.4.egg\websocket\_core.py", line 24, in <module>
    import socket
  File "D:\bitstamp\socket.py", line 3, in <module>
    from websocket import create_connection
ImportError: cannot import name 'create_connection'

Python 3.4 中是否存在问题或者我这样做不正确？

Answer 1

Python 3.4 没有任何问题。看来您可能缺少 websocket-client 包。

请通过在终端中运行命令来安装此软件包，如下所示，这应该可以解决您的问题。

pip install websocket-client
