Django ImportError:无法导入名称日期范围

我正在用PostgreSQL作为后端设置新的Django项目。我正在使用pip安装软件包。以下是在新环境中安装的要求

Django==1.9
argparse==1.2.1
djangorestframework==3.3.3
psycopg2==2.6.1
wsgiref==0.1.2

我不知道我在哪里犯了错误。请帮助我配置新项目。请给我一步一步的过程来配置新环境

Django==1.9
argparse==1.2.1
djangorestframework==3.3.3
psycopg2==2.6.1
wsgiref==0.1.2

错误堆栈为

from psycopg2.extras import DateRange, DateTimeTZRange, NumericRange
ImportError: cannot import name DateRange

---

对我有用。您能否

导入psycopg2

和

导入psycopg2.extras

我知道这对聚会来说太晚了，但显然使用

psycopg2二进制文件对我来说很有效

Djano
2.2.9
和Djongo
1.3.0
未能导入
psycopg2
，出现以下错误：
