Django > python manage.py runserver时报错。

Database returned an invalid datetime value. Are time zone definitions for your database installed?

解决方案：

修改settings.py的时区变量。

修改前：

LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'UTC'

USE_I18N =True

USE_L10N =True

USE_TZ = True

修改后：

LANGUAGE_CODE ='zh-hans'

TIME_ZONE ='Asia/Shanghai'

USE_I18N =True

USE_L10N =True

USE_TZ =False

运行成功。
