Deployment

Hi,

I was working today on the deployment of my django project that used django-cities-light.
Once the project is cloned on the server. And when executing migrations I got this error :

Applying cities_light.0009_auto_20190202_0257...Traceback (most recent call last):

ValueError: Table cities_light_city does not exist

SOLUTION :
The solution is to comment : 'cities_light' in your settings

INSTALLED_APPS = [
    ...
    # 'cities_light',
    ...
] 

If you want to populate your cities, regions and countries models please load fixtures of your project (mode : development)
