不确定我的herokuapp无法部署的原因。我正在python 3.6.5上构建一个烧瓶应用程序。我的应用程序在本地服务器上运行完全正常。两个月前应用程序在python 3.6.4上正确部署了应用程序，但我收到了升级到3.6.5的警告。在3.6.4和3.6.5下，我的应用程序因此错误而崩溃。这是heroku-18堆栈的错误吗？我检查了https://github.com/heroku/heroku-buildpack-python/issues/680，但我不知道它对我有多大帮助。我真的很感激一些帮助。谢谢！

您的requirements.txt格式不正确。
在我看来，您已使用pip list生成了它。您希望在生成pip freeze时使用requirements.txt。

requirements.txt的格式很奇怪。有关正确的格式示例，请参阅https://devcenter.heroku.com/articles/python-pip。详细文档位于https://pip.pypa.io/en/stable/reference/pip_install/#requirements-file-format
