如何修复“discord.errors.ClientException：命令踢已经注册。”错误？

Question

我在discord.py中创建一个discord bot，它会踢任何发送某个字符串的成员，但是我收到错误“discord.errors.ClientException：命令踢已经注册了”。

bot = commands.Bot(command_prefix=',')
@client.event
async def on_message(message):
    if message.author == client.user:
    return    

    if "kick me"in message.content:
        @bot.command(name="kick", pass_context=True)
        @has_permissions(kick_members=True)
        async def _kick(ctx, member: Member):
            await bot.kick(member)

我没有踢这个成员，而是得到了这个可爱的追溯：

Ignoring exception in on_message

discord.errors.ClientException: Command kick is already registered.

每当发送消息!kick me时，您将重新注册该命令。该命令应位于脚本或cog的顶层，而不是每次调用事件时都重新创建。

bot = commands.Bot(command_prefix=',')

@bot.event
async def on_message(message)
    ...
    await bot.process_commands(mesage)

@bot.command(name="kick", pass_context=True)
@has_permissions(kick_members=True)
async def _kick(ctx, member: Member):
    await bot.kick(member)
