Python Django应用程序与Gunicorn一起失败，与Runserver一起正常

为gunicorn开始脚本编辑

我试图调试一个在本地工作的应用程序，但在部署到Heroku时遇到了问题。使用heroku local或gunicorn threepoints.wsgi:application，我可以看到这个堆栈跟踪

我不确定这里出了什么问题

您的gunicorn回溯告诉您问题：

ImportError:没有名为wagtail的模块

因此，您需要确保wagtail是重要的。通常这意味着

pip安装wagtail

，并在您的virtualenv中使用python运行gunicorn：

---

gunicorn--pythonpath=/path/to/virtualenv/bin/python threepoints.wsgi

gunicorn--pythonpath=/path/to/virtualenv/bin/python threepoints.wsgi

请从Procfile

web:gunicorn threepoints.wsgi--log file-

中提供您的gunicorn启动脚本，这在终端中通过

gunicorn threepoints.wsgi:application

和

gunicorn threepoints.wsgi

进行确认虚拟人？如果是,，virtualenv是否包含所有必要的软件包，gunicorn是否配置为使用virtualenv？在我看来，您没有在项目的虚拟环境中运行gunicorn。请从Procfile
