我已经试过最一切我能找到，我甚至改变了我的app.run（）清空而不是app.run(host='0.0.0.0', port=int(os.environ.get('PORT', 33507)))试图允许heroku自己定义（我相信这导致了H20错误，这已被改回）。

我proc文件是：

web: python project.py 

，被 pip freeze > requirements.txt

该项目使用VM始建产生我requirements.txt，所以我甚至试图消除Vagrantfile，没有效果。

任何帮助非常感谢，我感到茫然，谢谢！

Answer 1

在project.py我错过了import os声明

解决的问题。
