Django database

I am using django since last one year but I faced a new problem.
Recently I created a project in django using django-admin startproject projectname and it created all files except db.sqlite3 file.
May someone please help me out of it.
Thank you!

After doing the startproject, did you do the ./manage.py migrate?

What version of Python are you using? What version of Django? What operating system are you using? Have you tried creating a different project in a different directory? Can you show a directory listing of what was created?
