django-Unknown command: 'syncdb'

The sqlall management command was removed in Django 1.9, along with syncdb.

Since Django 1.7, you shouldn't use syncdb. Instead, you should create migrations with makemigrations and perform the migrations with migrate. If you work through the polls tutorial, it explains how to use migrations.

There is now an sqlmigrate command that displays the sql commands for a specific migration, without performing the migration.
