没有名为'；dns'；python

我正在尝试使用mysql制作一个discord机器人体验系统。我已将数据库全部设置好，但当我尝试将其导入脚本时，始终出现以下错误：

Traceback (most recent call last):

我不知道如何修复它，任何帮助都将不胜感激（抱歉，如果我弄错了任何编程术语，我对它还是相当陌生），提前谢谢

你能分享一些关于你的环境的信息吗？例如，您正在使用哪些版本的软件包？是的，我正在使用visual Studio 2019，我相信它已经完全更新，并且我也在使用最新版本的mysql。

import os
import discord
import mysql.connector
from discord.ext import commands


client = discord.Client()

token = *blank*
Guild = os.getenv('DISCORD_GUILD')


bot_prefix = "C"

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


chirpDataBase =  mysql.connector.connect(host = *blank*, user = *blank*, passwd = *blank*, database = "ChirpBotUserLevels", auth_plugin = "mysql_native_password")

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




client.run(token)
