Django 错误之 No module named ‘MySQLdb’

报错如下：
File "/usr/local/python3/lib/python3.4/site-packages/django/db/backends/mysql/base.py", line 27, in <module>

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb'

MySQLdb 只适用于python2.x，。在python3.x的替代品是： import pymysql

 

解决办法：

base.py 文件同目录下的__init__.py文件新增如下两行：

vi /usr/local/python3/lib/python3.4/site-packages/django/db/backends/mysql/__init__.py

import pymysql
pymysql.install_as_MySQLdb()

 

如果还报如下错误：
AttributeError: module 'pymysql' has no attribute 'install_as_MySQLdb'

解决方法：
pip uninstall PyMySQL3
pip install -U --force-reinstall pymysql
