Django超级用户创建无响应

Question

我一直在尝试创建一个超级用户，但是最终我没有响应，并且在我填写密码后一直处于闲置状态。

(venv) [root@ubuntu:~/folder/pfg]$ python3 manage.py createsuperuser
Exception in importing from settings_local, continuing without
No module named 'pfg.settings_local'
System check identified some issues:

WARNINGS:
content.Item.category_measures: (fields.W340) null has no effect on ManyToManyField.
content.Item.vocab_items: (fields.W340) null has no effect on ManyToManyField.
Username (leave blank to use 'root'): django
Email address: cewehuj@email-server.info
Password:
Password (again):

即使在python3 manage.py migrate期间也发生了异常，但是此后的所有检查都正常，所以我希望异常不是那么严重。
