doesn\'t declare an explicit app_label and isn\'t in an application in INSTALLED_APPS.

2. 在添加一个生日字段 (日期类型)时报错:
You are trying to add a non-nullable field \'email\' to user without a default; we can\'t do that (the database needs something to populate existing rows).
Please select a fix:
1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
2) Quit, and let me add a default in models.py
解决:输入 1 会显示
Please enter the default value now, as valid Python
The datetime and django.utils.timezone modules are available, so you can do e.g. timezone.now
Type \'exit\' to exit this prompt
输入 timezone.now
