我使用Windows 7开发使用PostgreSQL 9.3作为数据库的Django 1.3.7。在settings.py我设置了DATABASE_ENGINE = 'django.db.backends.postgresql_psycopg2'，但当我尝试执行python manage.py syncdb时出现此错误：
C:\Django-Proj\myproj\myproj>python manage.py syncdb

对于Python扩展程序包，有大量的非官方Windows二进制文件列表，对Windows用户非常有用。

转到链接，下载并安装它，你就可以了。
干杯！

不要尝试为Windows编译psycopg2。您将需要Visual Studio安装或Windows SDK以及各种其他混乱。
