TypeError:注册的事件必须是协程函数discord.py

Question

import discord, asyncio, time, discord.guild, random, os, youtube_dl
import os
import asyncio
import math
import random
import youtube_dl
import json
from discord.ext import commands, tasks
from discord.ext.commands import Bot, guild_only
from itertools import cycle

def get_prefix(client, message):
with open('prefixes.json', 'r') as f:
prefixes = json.load(f)

return prefixes[str(message.guild.id)]

@client.event
async def on_ready():
change_status.start()
print('Bot is online')

@tasks.loop(seconds=3600)
async def change_status():
await client.change_presence(status=discord.Status.idle, activity=discord.Game(next(status)))

@client.event
def on_guild_join(client, message):

prefixes[str(message.guild.id)] = '.'
with open('prefixes.json', 'w') as f:
json.dump(prefixes, f, indent=4)

@client.event
async def on_guild_remove(guild):

prefixes = json.load(f)

prefixes.pop(str(guild.id))
with open('prefixes.json', 'w') as f:
json.dump(prefixes, f, indent=4)

@client.command(pass_context = True)
async def prefix(ctx, prefix):

prefixes[str(ctx.guild.id)] = prefix

错误为-追踪(最近一次通话(：文件"；c： \Users\PC\OneDrive \Documents\3mbot\main code\bot.py"，第71行，indef on_ild_join(客户端，消息(：文件"；C： \Users\PC\AppData\Local\Programs\Python39\lib\site-packages\discord\client.py"；，线路1002，在事件中raise TypeError("注册的事件必须是协程函数"(TypeError：注册的事件必须是协同程序函数

我使用的是带有最新pip的python 3.9.0。和最新的不和谐.py github。

Answer 1

它是协同程序

async def on_guild_join

不是

def on_guild_join
