我想在我的 django models.py 中进行此导入：

from django.contrib.postgres.fields import ArrayField

我阅读了此文档https://docs.djangoproject.com/en/dev/ref/contrib/并在 settings.py 的 INSTALLED_APPS 中添加了“django.contrib.postgres”，但是当我尝试同步我的数据库或运行服务器我得到“ImportError：没有名为 postgres 的模块”

还有什么我应该做或安装的吗？django.contrib.postgres 是核心发行版的一部分，对吗？

这是回溯：

django.contrib.postgres将是1.8发布的一部分。

幸运的是，django 中有几个非官方的 postgresql 数组实现。其中最值得注意的是djorm-pgarray。当 Django 1.8 最终推出时，另一个选项是django-dbarray，迁移应该不会太困难。
