为什么我的on_消息事件不起作用（discord.py）

Question

我正在制作一个工作正常的不和谐机器人，但是我想开始使用齿轮，因为我认为这是编写代码的更好的方式，但是现在我的on_message不再工作了，它也没有显示任何错误信息，我在整个互联网和所有的解释对我都不起作用，所以我决定在这里问。这是我的代码：

from discord.ext import commands

TOKEN = 'my token'

bot = commands.Bot(command_prefix="$")


class Interactions(commands.Cog):
    @commands.Cog.listener()
    async def on_message(self, message):
        msg = message.content
        hi = ["hi", "hello", "hi!", "hello!"]
        bye = ["bye", "good bye", "bye!", "good bye!"]

        # Messages in english
        if str(msg).lower() in hi:
            await message.channel.send('Hello!')

        if str(msg).lower == 'how are you?':
            await message.channel.send("I'm fine")

        if str(msg).lower == "what's your favorite food?":
            await message.channel.send("Sushi with sweet potato!")

        if str(msg).lower == "what do you eat?":
            await message.channel.send(
                "I don't eat, I'm just a simple bot :pensive:")

        if str(msg).lower == "are you fine?":
            await message.channel.send("Yes, I am")

        if str(msg).lower in bye:
            await message.channel.send("Good bye!")

def run():
    bot.add_cog(Interactions(bot)
    bot.run(TOKEN)


if __name__ == "__main__":
    run()

Answer 1

导入：

from discord.ext.commands import command, Cog

代码的其余部分：

TOKEN = 'my token'

bot = commands.Bot(command_prefix="$")


class Interactions(commands.Cog):
    @commands.Cog.listener()
  
    async def on_message(self, message):
        pass

这应该工作，如果不只是平我；）
