pymysql issue 'NoneType' object has no attribute 'encode'

Hi i'm trying to use pymysql. Here is the simpliest code

import pymysql
conn开发者_开发百科 = pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd=None,
                       db='newbase')

and i'm getting error: 'NoneType' object has no attribute 'encode'. i'm using easyphp5.3.6.0 What should i do ?

Looks like there is a problem with passwd=None parameter. Try to specify password as some string or do not pass this parameter.
