Problem connecting MySQL in Python 3.4

I just installed my virtual environment, I installed PyMysql and created a project, but when trying to start a python manage.py startapp nome APP, the following problem occurred:

Error loading MySQLdb module: No module named 'MySQLdb'

How can I configure MySQL and resolve this?

My settings.py :

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'meudb',
        'USER': 'root',
        'PASSWORD': '123',
        'HOST': 'localhost',
    }
}
