Gunicorn 不会运行 Django with WSGI

Question

我正在尝试运行我的 django 项目与 gunicorn 但出现错误。为了测试，我通过运行ning 以下命令创建了所有新内容：

virtualenv test_gunicorn
source test_gunicorn/bin/activate
pip install django gunicorn
cd test_gunicorn/
mkdir projects
cd projects/
django-admin startproject test_gunicorn
cd test_gunicorn/
gunicorn test_gunicorn/wsgi:application

但仍然遇到与我在原始项目中遇到的完全相同的错误。以下是错误：

这是 pip freeze 的输出：

Django==1.8.3
gunicorn==19.3.0

我是不是哪里做错了，还是 Django 或 gunicorn 有问题？

Answer 1

错误提示您传递的是文件路径而不是 Python 模块路径。你的 gunicorn 调用应该是：

gunicorn test_gunicorn.wsgi:application

Answer 2

您应该以 gunicorn test_gunicorn.wsgi:application 启动 gunicorn（注意 test_gunicorn 和 wsgi 之间的点而不是斜线）。基本上，语法与在 Python.

中编写 import 语句时的语法相同
