今天用peewee来连接mysql

from peewee import *
#建立连接mysql时的必要参数
db = MySQLDatabase('student',host ='localhost',user='root',passwd='123456')

db.connect

运行后，spyder一直报错

File "C:\ProgramData\Anaconda3\lib\site-packages\peewee.py", line 3981, in _connect
raise ImproperlyConfigured('MySQL driver not installed!')

ImproperlyConfigured: MySQL driver not installed!

开始以为是pymysql没有配好，于是单独测试pymysql，发现能正常运行，

后按报错信息找到peewee.py的3981行，如下：

 if mysql is None:
     raise ImproperlyConfigured('MySQL driver not installed!')

将这两行注释掉，再测试peewee，不再报错。后尝试连库写表成功
