AttributeError: 'Member' object 没有属性 'client'

Question

I am a new user of discord.py, and i'm facing an issue with a simple code:

from dotenv import load_dotenv

import discord
from discord.ext.commands import Bot
import os

load_dotenv()


class Bothoven:
    def __init__(self):
        self.version = 0.1
        self.client = discord.Client()
        self.bot = Bot(command_prefix='$')

        @self.bot.event
        async def on_ready():
            print('We have logged in as {0.user}'.format(self.bot))

        @self.bot.command()
        async def test(ctx):
            print(ctx)
            await ctx.send("oui maitre")

        self.bot.run(os.getenv("BOT_TOKEN"))

When I run it, everything seems good, the bot prints:

We have logged in as Bothoven#9179

But when I type something in the guild, it rises an exception:

Ignoring exception in on_message
Traceback (most recent call last):
  File "D:\PROJETS\Bothoven\venv\lib\site-packages\discord\client.py", line 343, in _run_event
    await coro(*args, **kwargs)
  File "D:\PROJETS\Bothoven\venv\lib\site-packages\discord\ext\commands\bot.py", line 942, in on_message
    await self.process_commands(message)
  File "D:\PROJETS\Bothoven\venv\lib\site-packages\discord\ext\commands\bot.py", line 935, in process_commands
    if message.author.client:
AttributeError: 'Member' object has no attribute 'client'

I understand the error, and I agree that author has no attribute client, but this statement is in bot.py, a library file.

Have you some idea of how to proceed?

I'm runing python3.8 and discord.py 1.6

EDIT :

Despite pip was telling me all packages were up to date, deleting my venv and rebuilding it resolved my issue.

There are a few things wrong with your Cog setup:

• You have to use commands.Cog.listener() to exploit events
• To create commands, use the commands.command() decorator
• Your self.bot definition is wrong and you don't need self.client

Here how you would setup your cog correctly:

from os import environ
from discord.ext import commands 

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

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

    @commands.Cog.listener()
    async def on_ready():
        print('Logged in as {0.user}'.format(self.bot))

    @commands.command()
    async def test(ctx):
        print(ctx)
        await ctx.send("Oui maître")

bot.add_cog(Bothoven(bot))
bot.run(environ["BOT_TOKEN"])

EDIT: Turns out it was a venv issue, re-building it solved the problem.
