Heroku和Django：无法检测到此应用程序的默认语言

问题描述

我遵循了教程(Link here)下的说明。我甚至将runtime.txt文件包含在正确的Python版本中。我到处都找过了，但似乎没有解决办法。我的GitHub项目参考链接：

错误消息：

解决方案

对于将来的读者，解决方案与@hansTheFranz的注释相同，但从命令行：

• 在应用创建时：heroku create --buildpack heroku/python app_name

• 对于现有应用：heroku buildpacks:set heroku/python

另外，官方Heroku Buildpack: Python文档可能会有所帮助。
