Discord 音乐机器人不读取命令

Question

所以，我正在尝试制作一个不和谐的音乐机器人，并且每当我使用播放命令时我都会收到这个错误，我认为它没有加载齿轮或与此有关。这是我的主要功能

这是我在 music_player 类the error that I'm getting once I run the code 中的命令

import discord
from discord.ext import commands

from youtube_dl import YoutubeDL

intents = discord.Intents.default()
intents.message_content = True

bot = commands.Bot(
    command_prefix=commands.when_mentioned_or("!"),
    description='Relatively simple music bot example',
    intents=intents,
)


@bot.event
async def on_ready():
    print(f'Logged in as {bot.user} (ID: {bot.user.id})')
    print('------')


bot.add_cog("cogs.music_player")

                if self.isplaying == False:
                    await self.play_song(ctx)




I was expecting the program to play a song or atleast join thet voice channel but apparently it says the command is not found I've tried changing stuff with the cog but it didn't help so I'm fully lost at what I'm doing wrong.

您在类中引入了一个命令，所以它看不到它，将其移出

class music_player(commands.Cog):

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

@commands.command()
async def play(self, ctx, *, args):
    .
    .
    .
