discord py v2 中的自定义帮助命令 cog

Question

所以，在早期的discord py版本中，我有一个单独的cog用于帮助命令和follow命令

import discord
from discord.ext import commands

class HelpCommand(commands.HelpCommand):
    colour = 0x0dd2ff

    @commands.Cog.listener()
    async def on_ready(self):
        print("Cog loaded - HelpCommand.py")

    def footer(self):
        return f"{self.clean_prefix}{self.invoked_with} [command] for more information"

    def get_command_signature(self, command):
        return f"```{self.clean_prefix}{command.qualified_name} {command.signature}```"

    async def send_cog_help(self, cog):
        embed = discord.Embed(title=f"**{cog.qualified_name}** commands", colour=self.colour)
        if cog.description:
            embed.description = cog.description

        filtered = await self.filter_commands(cog.get_commands(),sort=True)
        for command in filtered:
            embed.add_field(name=command.qualified_name, value=command.short_doc or "No description")

        embed.set_footer(text=self.footer())
        await self.get_destination().send(embed=embed)

    async def send_command_help(self, command):
        embed = discord.Embed(title=command.qualified_name, colour=self.colour)
        if command.help:
            embed.description = command.help
        embed.add_field(name="Signature", value=self.get_command_signature(command))
        embed.set_footer(text=self.footer())

        await self.get_destination().send(embed=embed)




    async def send_bot_help(self, mapping):
        embed = discord.Embed(title="Bot Commands", colour=self.colour)
        description = self.context.bot.description
        if description:
            embed.description = description

        for cog, commands in mapping.items():
            if not cog:
                continue
            filtered = await self.filter_commands(commands, sort=True)
            if filtered:
                value = "\t".join(f"`{i.name}`"for i in commands)
                embed.add_field(name=cog.qualified_name, value=value)

        embed.set_footer(text=self.footer())
        await self.get_destination().send(embed=embed)


async def setup(bot):
    bot.help_command = HelpCommand()

我曾经像 main.py 中的其他齿轮一样使用

来调用这个齿轮

for filename in os.listdir('./cogs'):
        if filename.endswith('.py'):
            await bot.load_extension(f'cogs.{filename[:-3]}')

将库更新为discord py v2后，我将cogs调用命令更改为

async def load():
    for filename in os.listdir('./cogs'):
        if filename.endswith('.py'):
            await bot.load_extension(f'cogs.{filename[:-3]}')

适用于除帮助命令齿轮之外的所有齿轮。有人可以告诉我如何纠正这个错误吗

尝试放置

for filename in os.listdir('./cogs'):
        if filename.endswith('.py'):
            await bot.load_extension(f'cogs.{filename[:-3]}')

在

on_ready

加载齿轮
