我创建了一个discord机器人，基本上我想要一个清除所有通道的命令 .clear 我对其他命令没有任何问题，没有其他明确的命令。但是当我使用 .help ，它不显示clear命令&它不工作。哦，是的，我得到的错误是“忽略命令中的异常无：discord.ext.commands.errors.commandnotfound:command“clear”未找到”我的代码：

import discord
from discord.ext import commands
import random
from discord import Permissions
from colorama import Fore, Style
import asyncio

# imports for reference

@client.command
@commands.is_owner()
 async def clear(ctx):
    await ctx.message.delete()
    guild = ctx.guild
    for channel in guild.channels:
     try:
      await channel.delete()
      print (Fore.GREEN + f"{channel.name} was deleted" + Fore.RESET)
     except:
        print (Fore.RED + f"{channel.name} was not deleted" + Fore.RESET)
        return

# I fixed it, what I had to do was instead of @client.command I was meant to put @client.command()
