python - Heroku 部署失败 : pip. _vendor.packaging.requirements.InvalidRequirement : Invalid requirement, "' 版本解析错误'"

Question

不确定为什么我的 herokuapp 部署失败。我正在 python 3.6.5 上构建一个 Flask 应用程序。我的应用程序在本地服务器上运行得很好。两个月前，该应用程序在 python 3.6.4 上正确部署，但收到升级到 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？我查看了https://github.com/heroku/heroku-buildpack-python/issues/680但不知道它对我有什么帮助。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，您是使用pip list生成的。您希望在生成 requirements.txt 时使用 pip freeze。
