我使用Windows 7開發Django 1.3.7使用PostgreSQL 9.3作爲數據庫。我settings.py我設置DATABASE_ENGINE = 'django.db.backends.postgresql_psycopg2'但是當我嘗試執行python manage.py syncdb我得到這個錯誤：錯誤：無法找到vcvarsall.bat在windows7中安裝psycopg2
C:\Django-Proj\myproj\myproj>python manage.py syncdb

然後我嘗試安裝psycopg2，但它得到了一個錯誤：

有沒有人有關於一個想法我的情況？在此先感謝
可以標記答案接受，如果它幫你。 – ajkumar25
非常感謝，我從你那裏得到了最好的信息，最後下載了最新的psycopg2支持並在Python34中測試了工作 – haidarvm
