    ImproperlyConfigured: Error loading MySQLdb module: No module named _mysql
    

I have installed mysqlclient as it said here
<https://docs.djangoproject.com/en/1.8/ref/databases/#mysql-db-api-drivers>.
Than i have did manage.py syncdb and it had finished successfully. I have
checked database structure and it is ok - all data had migrated. But there is
still such error on my app start.

The Solution is: to use non-official libs <https://github.com/nakagami/django-
cymysql/> It is easy to install and configure with django:

    
    
    $ pip install cymysql
    $ pip install django-cymysql
    

Than just add this engine to django's settings.py:

    
    
    DATABASES = {
    'default': {
        'ENGINE': 'mysql_cymysql',
        'NAME': 'some_what_database',
        'HOST': ...,
        'USER': ...,
        'PASSWORD': ...,
       }
    }
    


Answer: Try this; this solved my issue

    
    
    pip install MySQL-python
