我正在尝试在 Heroku 上部署 Tornado。我可以使用这种方法运行一个简单的“hello world”应用程序：http: //kzk9.net/deploying-tornado-on-heroku-mac-os-x

但是在尝试 Tornado 演示应用程序“chatdemo”时，服务器崩溃并显示以下日志：

检查你的procfile和requirements.txt。如果有人在看，这里是部署在 Heroku 上的相同官方聊天演示的一个工作示例

您的 Procfile 应包含以下内容：

 web: python app.py

（将 app.py 替换为“chatdemo.py”或您的应用名称）

截至 2021 年 7 月，@avi 和 @apoclyps 提供的答案在 Tornado 6.1 上仍然可以正常工作。

我的 Tornado 网络应用程序的 Procfile 出现在下面。它也适用于 AWS：

web: python application.py --port=$port --logging=error
