Websocket 不会 function

Question

I am trying to use websockets to stream data from an API and I am receiving a attribute error. any help would be much appreciated!

import websocket

Stock_stream = 'wss://data.alpaca.markets/stream'

def on_open(ws)
#code

def on_message(ws, message)
#code

def on_close(ws)
#code

ws = websocket.WebSocketApp(Stock_stream, on_open=on_open, on_message=on_message, on_close=on_close)
ws.run_forever()

Traceback (most recent call last):
  File "C:\Users\engli\PycharmProjects\hello\Alpaca_script.py", line 385, in <module>
    ws = websocket.WebSocketApp(Stock_stream, on_open=on_open, on_message=on_message, on_close=on_close)
AttributeError: module 'websocket' has no attribute 'WebSocketApp'

WebSocketApp is also highlighted in yellow, it says, "cannot find reference 'WebSocketApp' in ' init .py' "

Thank you

It seems as if you are using the incorrect library. Erase the current "websocket" library and in the terminal type "pip install websocket-client". This should solve your problems.
