Question

我发现了一个发送最新删除消息的命令。在测试时，我发现当我删除一条消息时，它会向控制台发送一个回溯错误。这是回溯错误和代码。

忽略 on_message_delete 中的异常回溯（最近一次调用最后一次）： _run_event 中的文件“/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/client.py”，第 343 行等待 coro(*args, **kwargs) 文件“/home/runner/Isla/cogs/awp.py”，第 21 行，在 on_message_delete 如果 msg.author.client： AttributeError: 'Member' 对象没有属性 'client'
