ImportError: cannot import name execute_manager

[sabygo]

when syncdb was called it gave this error with django 1.6
python manage.py syncdb
Traceback (most recent call last):
File "manage.py", line 2, in
from django.core.management import execute_manager
ImportError: cannot import name execute_manager

when i searched for the error it said execute_manager has been completely removed in 1.6.
