谁能帮我解决这个错误？不和谐.py

Question

这样做的目的是查看用户是否没有管理消息权限，然后根据他们所说的内容发送一条消息，这可以工作，但它会用这个错误填充我的控制台。这是我收到的错误：

Traceback (most recent call last):

  File "C:\Python38\lib\site-packages\discord\client.py", line 312, in _run_event

    await coro(*args, **kwargs)

  File "C:\Users\cuzto\Desktop\DiscordBot.-py\cogs\events.py", line 106, in on_message

    if not message.author.permissions_in(message.channel).manage_messages:

  File "C:\Python38\lib\site-packages\discord\user.py", line 232, in permissions_in

    return channel.permissions_for(self)

  File "C:\Python38\lib\site-packages\discord\channel.py", line 146, in permissions_for

    base = super().permissions_for(member)

  File "C:\Python38\lib\site-packages\discord\abc.py", line 475, in permissions_for

    roles = member.roles

AttributeError: 'User' object has no attribute 'roles'

这是代码：

    @commands.Cog.listener()

    async def on_message(self, message):

        if not message.author.permissions_in(message.channel).manage_messages:

            if "discord.gg" in message.content.lower():

                await message.delete()

                await message.channel.send(f"temp, <@{message.author.id}>")

有人会告诉我如何解决这个问题吗？我尝试了很多事情，但我不知道还能做什么

消息在 DM 中发送，而不是在服务器中发送。当 DM 发送时，message.author将是一个 User 对象，正如您所知，在 DM 中没有角色，所以它是一个错误。当消息在服务器中发送时，message.author将是一个Member对象，Guild中的User成为Member，因为服务器中有角色，Member.roles将有效。检查消息是否没有公会属性，然后返回@commands.Cog.listener()async def on_message(self, message):&nbsp; &nbsp; if not message.guild: return&nbsp; &nbsp; if not message.author.permissions_in(message.channel).manage_messages:&nbsp; &nbsp; &nbsp; &nbsp; if "discord.gg" in message.content.lower():&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; await message.delete()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; await message.channel.send(f"temp, <@{message.author.id}>")
