我在AWS上的Ubuntu 14.04中设置了一个应用程序 – > Nginx – > UWsgi – > DJANGO APP.
当使用sqllite3时,应用程序运行完全正常,但是当我使用 django.db.backends.postgresql_psycopg2w作为我的数据库引擎时,它无法加载,我在uwsgi日志中找到了这个:

我使用apt-get安装了以下软件包:
libpq-dev python-dev postgresql postgresql-contrib Nginx python-pip
psycopg2 == 2.6.1包也安装在我的venv中.
任何人都可以指出我正确的方向,我现在已经搜索了几个小时,并且不知道它为什么会失败.
