从未等待过 discord.py 协程“Command.__call__”

Question

当我尝试运行该命令时，我总是收到此错误消息：discord.ext.commands.errors.ExtensionFailed：扩展 'cogs.unban' 引发错误：类型错误：cogs 必须从 Cog 派生 sys:1: RuntimeWarning: coroutine 'Command.call' 从未被等待

import discord
from discord.ext import commands

class unban(commands.Cog):

    def __init__(self, client):
        self.client = client

# Commandok

@commands.command()
async def unban(ctx, *, member): # unindent
    banned_users = await ctx.guild.bans() # unindent
    member_name, member_discriminator = member.split('#') # unindent

    for ban_entry in banned_users:
        user = ban_entry.user

    if (user.name, user.discriminator) == (member_name, member_discriminator):
        await ctx.guild.unban(user)
        await ctx.send(f'Unbanned {user.mention}')
    return

def setup(client):
    client.add_cog(unban(client))

我收到以下错误：

File "K:\Discord BOT\PythonX\Bot.py", line 74, in <module>
    client.load_extension(f'cogs.{filename[:-3]}')

Answer 1

class Administration(commands.Cog):
    def __init__(self,bot):
        self.bot = bot

    @commands.command()
    async def unban(self, ctx,*,member):
        # your function 

def setup(bot):
    bot.add_cog(Administration(bot))
