我不知道如何将 Cog 函数导入到我的不和谐机器人的 main.py 中

Question

我正在尝试制作一个 Discord 机器人，它将使我能够使用 cog 从另一个文件运行命令，但当我尝试将我的 Cog 添加到我的 main.py 文件时，它似乎出现问题。

这是我的 main.py 的代码：

import discord
import os
import asyncio
from discord.ext import commands

bot = commands.Bot(command_prefix="!", intents=discord.Intents.all())

async def load():
    for filename in os.listdir('./cogs'):
        if filename.endswith(".py"):
            cog_name = filename[:-3]  # Remove the '.py' extension
            cog_path = f'cogs.{cog_name}'  # Construct the full path to the cog
            try:
                bot.load_extension(cog_path)
                print(f"Loaded extension: {cog_name}")
            except commands.ExtensionAlreadyLoaded:
                print(f"Extension {cog_name} is already loaded.")
            except commands.ExtensionNotFound:
                print(f"Extension {cog_name} not found.")


@bot.event
async def on_ready():
    await bot.change_presence(status=discord.Status.dnd, activity=discord.Game('Playing Call of Duty: Modern Warfare 3'))
    print("--------------------------------------------")
    print("Bot is ready")
    print("--------------------------------------------")

@bot.command()
async def hello(ctx):
    await ctx.send(f"Hello there, {ctx.author.mention}!")



my_files = ["ban"]

for file in my_files:
    bot.load_extension(f"cogs.ban")

with open("token.txt") as file:
    token = file.read()
    
bot.run(token)

这是我的命令的代码，我希望它能够运行（它是一个禁止命令）：

import discord
from discord.ext import commands

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

    @commands.command()
    @commands.has_permissions(ban_members=True)
    async def ban(self, ctx, member: discord.Member, *, reason=None):
        await member.ban(reason=reason)
        await ctx.send(f"{member} has been banned!")

def setup(bot):
    bot.add_cog(Ban(bot))

每次运行它时，它总是给我以下错误消息：

2024-05-08 10:53:31 ERROR    discord.ext.commands.bot Ignoring exception in command ban
Traceback (most recent call last):
  File "/home/runner/DEATH-TO-THE-MPLA/.pythonlibs/lib/python3.10/site-packages/discord/ext/commands/core.py", line 235, in wrapped
    ret = await coro(*args, **kwargs)
  File "/home/runner/DEATH-TO-THE-MPLA/main.py", line 35, in ban
    await ctx.invoke(bot.get_command('ban'), ctx, member, reason=reason)  # Invoke the ban command defined in the Ban cog
  File "/home/runner/DEATH-TO-THE-MPLA/.pythonlibs/lib/python3.10/site-packages/discord/ext/commands/context.py", line 336, in invoke

  File "/home/runner/DEATH-TO-THE-MPLA/.pythonlibs/lib/python3.10/site-packages/discord/ext/commands/core.py", line 590, in __call__
    return await self.callback(context, *args, **kwargs)  # type: ignore
TypeError: ban() takes 2 positional arguments but 3 positional arguments (and 1 keyword-only argument) were given

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/runner/DEATH-TO-THE-MPLA/.pythonlibs/lib/python3.10/site-packages/discord/ext/commands/bot.py", line 1350, in invoke
    await ctx.command.invoke(ctx)
  File "/home/runner/DEATH-TO-THE-MPLA/.pythonlibs/lib/python3.10/site-packages/discord/ext/commands/core.py", line 1029, in invoke
    await injected(*ctx.args, **ctx.kwargs)  # type: ignore
  File "/home/runner/DEATH-TO-THE-MPLA/.pythonlibs/lib/python3.10/site-packages/discord/ext/commands/core.py", line 244, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: ban() takes 2 positional arguments but 3 positional arguments (and 1 keyword-only argument) were given

如果有人可以帮助我，我会很感激

我尝试在这里使用不同的帖子：如何将齿轮导入到我的 main.py 文件中？来解决这个问题，但是当我使用它时，它所做的只是导致以下错误：

/home/runner/DEATH-TO-THE-MPLA/main.py:38: RuntimeWarning: coroutine 'BotBase.load_extension' was never awaited
  bot.load_extension(f"cogs.ban")
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

Bot is ready

机器人本身运行了，但命令不起作用。

Answer 1

日志提到

  File "/home/runner/DEATH-TO-THE-MPLA/main.py", line 35, in ban
    await ctx.invoke(bot.get_command('ban'), ctx, member, reason=reason)  # Invoke the ban command defined in the Ban cog

在

ctx.invoke(bot.get_command('ban'), ctx, member, reason=reason)

中，您有效地提供了

ctx

两次。试试

ctx.invoke(bot.get_command('ban'), member, reason=reason)

这部分代码并未包含在您与我们分享的代码中。如果您仍然遇到问题，请分享所有相关代码。

Answer 2

我过去制作了一个音乐机器人，它也使用齿轮，我通过 asyncio 导入齿轮，如下所示：

import asyncio

from NAME_OF_YOUR_COG_FILE import NAME_OF_YOUR_CLASS_INSIDE_THE_COG

loop = asyncio.new_event_loop()
loop.run_until_complete(bot.add_cog(NAME_OF_YOUR_COG_FILE(bot)))

希望我能帮上忙！如果没有的话请联系我！
