Discord Bot无法在VSCode上运行

机器人.py

#机器人.py
import os

import discord
from dotenv import load_dotenv

load_dotenv()
TOKEN = os.getenv('DISCORD_TOKEN')

client = discord.Client()

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

client.run(TOKEN)

.环境

# .环境
DISCORD_TOKEN = {token}

遵循来自的教程https://realpython.com/how-to-make-a-discord-bot-python/，尝试启动机器人，但它无法运行，出现错误，似乎与无法登录和(事件循环已关闭)有关.也不确定我应该如何将我的令牌包含在{}中或什么都不包含.我知道用我的实际令牌替换token关键字.
