我是python新手，刚开始是实现小程序，现在尝试连接数据库，我安装了python 3.4和mysql.connector 2.0.4。

下面是我用来连接数据库的代码#!"C:\python34\python.exe"

import sys

import mysql.connector

print("Content-Type: text/html;charset=utf-8")

print()

conn = mysql.connector.connect(host='localhost:8051',

database='test',

user='root',

password='tiger')

if conn.is_connected():

print('Connected to MySQL database')

但我得到的错误如下所示。由于安装环境错误或其他原因，无法获取发生此错误的原因

请建议Traceback (most recent call last):
