Discord.py机器人报错create_dm未定义如何封禁用户后发送DM通知

问题修复方案

核心错误原因

create_dm是discord.Member实例的内置方法，不是全局函数，不能直接调用create_dm(member)，需要通过成员对象调用await member.create_dm()
非Cog类下的@client.command装饰的命令函数不需要加self参数，保留self会触发参数匹配错误
逻辑顺序错误：先执行封禁操作后，bot可能失去和被封禁用户创建DM会话的权限，导致通知发送失败，需要先发送DM再执行封禁
笔误：封禁操作后的公屏提示文案写的是kicked，和实际操作不符

修正后完整代码

import discord
from discord.ext import commands  

intents = discord.Intents(messages=True, guilds=True, reactions=True, members=True,presences=True,guild_messages=True)

client = commands.Bot(command_prefix="!dc ", intents=intents)

@client.event
async def on_ready():  
    print("I am ready!")

@client.command(aliases=["ban"])
@commands.has_role("admin")
async def ban_user(ctx, member: discord.Member, *, reason=None):
    # 先创建DM发通知
    dm_channel = await member.create_dm()
    await dm_channel.send("You've been banned from the server.You won't join the server until admin opens your ban.")
    # 再执行封禁操作
    await member.ban(reason=reason)
    await ctx.send(f"{member} has been banned from server.")
        
@client.command(aliases=["kick"])
@commands.has_role("admin")
async def kick_user(ctx, member: discord.Member, *, reason=None):
    # 踢人也可以参考上面的逻辑先通知再操作
    dm_channel = await member.create_dm()
    await dm_channel.send("You've been kicked from the server.")
    await member.kick(reason=reason)
    await ctx.send(f"{member} has been kicked from the server.")

client.run(myToken)
