类型错误：on_message() 缺少 1 个必需的位置参数：“成员”discord.py

Question

I am having a problem with the report command I am working on. Whenever I run the command on my discord server, the error "TypeError: on_message() missing 1 required positional argument: 'Member'" comes up. If anyone knows how to solve this problem can you tell me? Thank you for taking your time to read this.

# bot.py
from discord import Member
import os
import discord
from dotenv import load_dotenv
load_dotenv()
DISCORD_TOKEN = ''

client = discord.Client()

@client.event
async def on_ready():
    print(f'{client.user} has connected to Discord!')

@client.event
async def on_message(message, Member):

    Member = discord.Member(Member)

    if message.author == client.user:
        return

    if message.content.startswith('$report ', Member.mention):
        Sends = 'That user has been reported!'
        await message.channel.send(Sends)

client.run(DISCORD_TOKEN)

I can see that your new to discord.py. First of all, the on_message function does not take member. It only takes message. When you add an event to your code you always want to check the Event Reference and check the paramters for that event. You cannot add or remove paramaters. For this case your code would start like this

@client.event
async def on_message(message)

To get the member you would use:

member = message.author

Also I recommend you use commands

from discord.ext import commands

It will be a lot easier and you can add your own paramaters. I've made an example of what you're doing with your on_message function in a command

@client.command
async def report(ctx, member : discord.Member, reason=None)
    await ctx.send(f"Reported {member.mention} for {reason}")

Also remember if you have an on_message function your commands wont work unless you use bot.process_commands at the end. Read the FAQ on how to do that.
