我想知道为什么会出现以下情况 xlOpenPort 失败 (XL_ERR_INVALID_CHANNEL_MASK)

如何解决我想知道为什么会出现以下情况 xlOpenPort 失败 (XL_ERR_INVALID_CHANNEL_MASK)

这是我正在尝试的代码：

import can
bus = can.interface.Bus(channel=0,bustype = 'vector')

这是我按原样运行脚本时收到的错误错误。

Traceback (most recent call last):
  File "C:/Users/xyz/Desktop/cantest2.py",line 2,in <module>
    bus = can.interface.Bus(channel=0,bustype = 'vector')
  File "C:\Users\xyz\AppData\Local\Programs\Python\python37\lib\site-packages\can\interface.py",line 127,in __new__
    return cls(channel,*args,**kwargs)
