使用gunicorn部署Django没有名为ImportError的模块：没有名为validation的模块

我正在尝试使用 nginx、gunicorn 和 virtualenv 部署我的 Django 项目。但我在运行此评论时遇到以下错误

sudo gunicorn_django --bind test.com:8001

Log :

Traceback (most recent call last):

该项目在本地运行良好。

这是我的设置.py file :

我在 virtualenv 上的 pip 列表：

姜戈 (1.7.4)

枪兽 (19.2.1)

点 (6.0.8)

安装工具 (12.0.5)

--Python 2.7.8

改变gunicorn_django to gunicorn newApp.wsgi:application应该解决这个问题。

Using gunicorn_django不再推荐。这是因为它调用django_wsgi.py它已被弃用并引发导入错误。
