Discord py MemberNotFound 异常

Question

@commands.command()
async def mute(self, ctx, member : discord.Member = None):
  try:
    if isinstance(member, discord.Member):
      await member.edit(mute=True)

    elif member is None:  #setting the command to mute selected member        
    member=get(ctx.guild.members, id=Charles_id) 
      await member.edit(mute=True)        

  except discord.HTTPException:
    await ctx.channel.send(f"User {member.mention} isn't connected to voice channel")
  except discord.ext.commands.errors.MemberNotFound("@everyone"):
    vc = ctx.author.voice.channel
    for user in vc.members:  
      await user.edit(mute=True)

因此，我正在尝试发出使上述播放器静音的命令。 默认情况下，它应该使我们的朋友查尔斯静音。 唯一的问题是默认角色（@Everyone）。 我挣扎了很多，但最终我想出了一个可行的想法。 可悲的是它并没有真正起作用。 该计划是尝试获取成员，如果成员是@everyone，它将运行一个错误，该错误将触发除了并最终会做它的事情。 我对编程很陌生，所以我希望能得到有用的教训，干杯！

追溯如下：

我认为错误不言自明。 @everyone不是会员，所以你不能转换它。

另一种选择是手动转换它：

async def mute(self, ctx, *, member_string: str):
    if member_string == "@everyone":
        return await ctx.send("You can't mention everyone")
 
    # Converting the string to a `discord.Member` obj
    member = commands.MemberConverter.convert(ctx, member_string)
    if member.voice is None:
        return await ctx.send("Member isn't in a voicec channel") # Exiting if the user isn't connected to any vs channel

    await member.edit(mute=True)
