Discord.py：如何在不使用 Cogs 的情况下在 OOP 中编写 discord 机器人？ 我在尝试时遇到了错误

Question

I have been working on discord bot for a pretty long time and now I decided that it is time that I start using the Bot with OOP as I am getting into it. I have given it a simple try and tried to run it but it was showing some error which I didn't understand.

When I use the following code:

import discord
from discord.ext import commands

class JervisI(commands.Bot):
    def __init__(self, command_prefix, case_insensitive, botintents):
        self.command_prefix = command_prefix
        self.case_insensitive = case_insensitive
        self.botintents = botintents


J1 = JervisI(command_prefix="!", case_insensitive=True, botintents=discord.Intents.all())
J1.run("---HIDDEN TOKEN---")

When I run the code I get this error:

Traceback (most recent call last):
  File "c:\Users\Bhavyadeep\Desktop\Discord Bot (Python)\PHub-Bot-1\jervis-1.py", line 12, in <module>
    J1.run("---HIDDEN TOKEN---")
  File "c:\Users\Bhavyadeep\Desktop\Discord Bot (Python)\PHub-Bot-1\The-Naval-Historian\lib\site-packages\discord\client.py", line 692, in run
    loop = self.loop
AttributeError: 'JervisI' object has no attribute 'loop'

I have no idea on how to do it. Please do let me know where the error is.

Thank You: :D

You're overwriting the __init__ method of commands.Bot , if you take a look at the source code you can see that it's pretty long and important, you're gonna get a ton of AttributeError s if you don't call the "original" __init__ method:

class JervisI(commands.Bot):
    def __init__(self, command_prefix, case_insensitive, botintents):
        super().__init__( # Same arguments that you pass to `commands.Bot(...)`
            command_prefix=command_prefix, 
            case_insensitive=case_insensitive,
            intents=botintents
        )

        self.command_prefix = command_prefix # You don't need to create this, it already exists
        self.case_insensitive = case_insensitive
        self.botintents = botintents
