If you're getting errors about missing database tables even when you
run manage.py makemigrations, then that would mean you'll get that
same error every time you run manage.py, regardless of what command
you run. makemigrations does not access the database, it only inspects
existing migration files, and compares them to the current model
definitions.

The error you are getting is most likely because you're accessing the
database on import (i.e. somewhere at module level you are making
database queries). If that is indeed the case, then you would get the
exact same error even with the old syncdb. However, it is hard to tell
for sure, since you have not provided the full traceback.
