我正在关注Heroku 上的 Django 入门教程
当我尝试使用 Foreman 在 Gunicorn 上运行 Django 应用程序时，我得到下一个错误回溯：

SIGTERM received

Procfile 位于项目的根目录中，包含：

网站：gunicorn hepcat_server.wsgi

settings.py 位于 hepcat_server 目录

当我使用$ python manage.py run_gunicorn
gunicorn 成功启动时，我看到了默认的 Django 页面

在关注您使用的 Heroku 设置页面时，我遇到了同样的问题。我在此页面上找到了解决方案。我已将其复制到这里以供后代使用：

在 django 项目的根目录中，创建 Procfile 文件。然后在网上写下这个：sh -c "cd djangoproject && gunicorn djangoproject.wsgi"。然后在同一位置创建另一个名为 .env 的文件，将 DJANGO_SETTINGS_MODULE=djangoproject.settings 写入其中，这将帮助您设置无法在 djangoproject.wsgi 模块中设置的所需环境变量。运行 foreman start 以进行测试。给出下面的问题，这应该是不言自明的。

部署时，在 heroku 中创建应用程序后，使用命令 heroku config:set DJANGO_SETTINGS_MODULE=djangoproject.settings 设置环境变量，这是因为在文件 djangoproject/djangoproject/wsgi.py 运行之前部署失败。

请记住将“djangoproject”替换为您的 django 项目的名称。
