Question

我最近更新了一个与Django rest framework 2.4.2一起使用的项目到新的3.1版本，但现在我得到了一个：

'module' object has no attribute 'HStoreField'

包括"/"

在内的所有端点都会发生这种情况

有什么建议吗？我的Django版本是1.8和python 2.7.6

安装Django 1.8的最新候选版应该可以解决这个问题。

您正在运行1.8.dev20140910173004，它已经支持某些Postgres字段，但尚未支持HStoreField。 Django REST框架仅检查django.contrib.postgres，然后假定HStoreField也可用。对于你的Django版本，情况并非如此。

如果pip install -u没有为您提供最新版本，请尝试删除并重新安装Django。

Django Rest Framework - ＆＃39;模块＆＃39;对象没有属性＆＃39; HStoreField＆＃39;
