【问题描述】：

我正在将 Heroku 上的一个项目迁移到 DO droplet。安装顺利，我python manage.py runserver 0.0.0.0:8000时一切正常。

我现在正在使用以下说明设置 gunicorn： https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-14-04

我激活虚拟环境，然后尝试--bind 0.0.0.0:3666 myproject.wsgi:application。我收到以下错误：

Traceback (most recent call last):

    raise ImproperlyConfigured(self.error_msg.format(self.namevar))
ImproperlyConfigured: Configuration cannot be imported, environment variable DJANGO_CONFIGURATION is undefined.

我的wsgi.py 看起来像这样：

# -*- coding: utf-8 -*-

import os

from configurations.wsgi import get_wsgi_application

application = get_wsgi_application()

我最初没有设置项目，所以我不确定有什么不同，或者在哪里看。

【解决方案1】：

使用此链接并将 DJANGO_CONFIGURATION 环境变量设置为您刚刚创建的类的名称，例如在 bash 中：

导出 DJANGO_CONFIGURATION=Dev

这么简单，我没有意识到这是设置为使用django-configurations
