Python on_ready未在cog文件discord.py中触发

我有这样的代码:

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

    @commands.Cog.listener()
    async def on_ready(self):
        print("TEST")

    @app_commands.command(name="setup", description="setup")
    async def setup(self, interaction):
        await interaction.response.send_message("test")


async def setup(bot):
    await bot.add_cog(Test(bot))

问题是，当加载齿轮时，它不会打印"test"，而且on_ady中的代码似乎没有触发.

我在输出中没有得到任何错误，我认为ON_READY没有被触发，但是async def on_message(self, message)可以很好地工作.这可能是什么问题呢？

Main.py如下所示:

    import os
    import discord
    from discord.ext import commands
    
    intents = discord.Intents.all()
    intents.members = True
    bot = commands.Bot(command_prefix="!", intents=intents)
    
    
    async def load():
        print("Loading cogs:")
        for filename in os.listdir("./cogs"):
            if filename.endswith(".py"):
                print(filename)
                await bot.load_extension(f'cogs.{filename[:-3]}')
    
    
    @bot.event
    async def on_ready():
        print(f'Logged in as {bot.user.name}')
        await load()
    
    
    @bot.command()
    async def sync(ctx):
        if ctx.author.id == MY_USER_ID:
            b = await bot.tree.sync()
            await ctx.send("Currently synced " + str(len(b)) + " commands!")
            print("Sync command was issued, synced " + str(len(b)) + " commands!")
        else:
            await ctx.send('You must be me to use this command!')
    
    
    @bot.command()
    async def reload(ctx):
        if ctx.author.id == MY_USER_ID:
            print("RELOADING SELECTED COGS:")
            await ctx.send("Succesfully reloaded these cogs:")
            for filename in os.listdir("./cogs"):
                if filename.endswith(".py"):
                    await ctx.send(filename)
                    await bot.reload_extension(f'cogs.{filename[:-3]}')
        else:
            await ctx.send('You must be me to use this command!')
    
    
    with open('token.txt', 'r') as file:
        bot_token = file.read().strip()
    
    bot.run(bot_token)
