用pycharm开发django项目，所有的数据模型和管理员模型都创建好了，结果createsuperuser显示这个：
```python
C:\Users\tianf\PycharmProjects\examination\examination>python manage.py createsuperuser

ibute is specific to pytz's interface; please migrate to a new time zone provider. For more details on how to do so, see https://py

self.BASE_TIME_ZONE = tz_localzone.zone if hasattr(tz_localzone, 'zone') else tz_localzone.key
You have 19 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, comp
itation, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.
