Django AttributeError：'模块'对象没有属性'SubfieldBase'

Question

我正在使用django的旧版本创建的django项目。我的环境设置为最新的django版本（1.11.4）。 当我尝试python manage.py runserver，我得到这个：

Unhandled exception in thread started by Traceback (most recent call last): File

"/usr/local/lib/python2.7/dist-packages/django/utils/autoreload.py", line 228, in wrapper

from .fields import TimedeltaField File "/usr/local/lib/python2.7/dist-packages/timedelta/fields.py", line 18, 

in

class TimedeltaField(six.with_metaclass(models.SubfieldBase, models.Field)): AttributeError: 'module' object has no attribute 

'SubfieldBase'

所以，看来问题是与Django的timedeltafield包。我有该软件包的最新版本（0.7.10）。所以，我不明白为什么它仍然有一个问题与废弃的SubfieldBase。

任何想法我可以如何解决这个问题？

Answer 1

django-timedelta字段包不能用于Django 1.10+。从django-timedelta-field回购：

If you are using Django 1.8 or greater (and you really should be), then you should use the included DurationField() instead of this.

This field does not work with Django 1.10, and will probably not be updated to fix the issue(s).

下面是SubFieldBase从1.8 release notes弃用的解释。
