sent_message.py 报错

Created by: ourbest

File "/usr/local/lib/python3.6/site-packages/wxpy/api/messages/sent_message.py", line 88, in member if isinstance(Group, self.receiver):

    @property
    def member(self):
        """
        若在群聊中发送消息，则为群员
        """
        from wxpy import Group

        if isinstance(Group, self.receiver):
            return self.receiver.self

这个isinstance是不是参数搞反了
