How to solve the problem of cocould not import settings 'conf. local', djangoconf. local when django configures settings

For example

Django best practices and deployment: Nginx + Gunicorn + Supervisor (Ubuntu and CentOS)
Http://sfdye.com/articles/django-best-practice-and-deployment-with-nginx-gunicorn-and-supervisor/

O module named conf. local

This empty file must be created in the self-built folder before it can be scanned as a module by django ....
