我试图写一个基本的机器人，但似乎机器人不想加载我的轮齿，其中只包含一个简单的命令test。
当我尝试在机器人的DM和机器人加入的服务器中调用该命令时，没有任何React。

(discord) ~/source/bot » python main.py

main.py

intents = discord.Intents.all()
TOKEN = "XXX"

bot = commands.Bot(command_prefix="%", intents=intents)
logger = logging.StreamHandler(stream=sys.stdout)

@bot.event
async def on_ready():
  logging.info("Bot is ready")
  await bot.load_extension("mycog")

@bot.event
async def on_message(ctx):
  logging.info("Message received: %s", ctx.content)

async def main():
  utils.setup_logging(handler=logger)
  await bot.start(token=TOKEN)

asyncio.run(main())

mycog.py

class MyCog(commands.Cog):
  def __init__(self, bot: commands.Bot):
    self.bot = bot
    self.count = 0
  
  @commands.command(name="test")
  async def test(self, ctx):
    # It should log when called, but this isn't the case at the moment
    logging.info("Test function called")
    await ctx.send("Pong!")

async def setup(bot: commands.Bot):
  await bot.add_cog(MyCog(bot))
  logging.info("Setup function called")

我还尝试将bot.load_extension调用放在bot.start之前的main中，但也没有成功。
