discord.ext有故障吗？

Question

import discord
from discord.ext import commands
import random
import praw

cl = commands.Bot(command_prefix = '!')
reddit = praw.Reddit(client_id = "",
                    client_secret = "",
                    username = "",
                    password = "",
                    user_agent = "")
@cl.event
async def on_ready():
  print("Bot is ready, get ready to do wutever u want with it")

@cl.command()
async def meme(ctx, amount=50, subr="memes", filter="top"):
 all_submission = []
 subreddit = reddit.subreddit("subr")
 subs = subreddit.filter(limit = amount)
 for submission in subs:
   all_submission.append(submission)
 random_sub = random.choice(all_submission)
 name = random_sub.title
 url = random_sub.url
 em = discord.embed(title = name)
 em.set_image = url
 await ctx.send(embed=em)
 print("embed sent")


cl.run("")

当我运行它的时候，什么都没有出现，但是当我调试它的时候，它给我看了这个回溯错误的东西！

It appears that you are using PRAW in an asynchronous environment.
It is strongly recommended to use Async PRAW: https://asyncpraw.readthedocs.io.
Ignoring exception in command meme:

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

这就是我所说的错误，就像告诉我下载异步普拉w一样奇怪，我从来没有遇到过问题，请帮助它是必要的。

问题是，与Bot.event装饰器不同，Bot.command解码器是一个必须调用的函数，所以用@cl.command()替换@cl.command
