Heroku：从非主源分支推送更新

Question

我正在尝试将我的应用程序上传到 heroku，但 heroku/python buildpack 没有构建我的应用程序并说它与它不兼容，我有一个 Procfile 和一个 requirements.txt 文件。添加并提交了所有必需的文件，该应用程序在我的本地计算机上完美运行。

这是需求文件：

这是 Procfile：

这是输出：

$ git push heroku master
Enumerating objects: 197, done.
Counting objects: 100% (197/197), done.

我已经尽我所能来解决这个问题。我多次删除了 heroku 应用程序并再次创建它，我尝试更改 requirements.txt 文件中的模块版本，但似乎没有任何效果。非常感谢您的帮助
注意：我正在从不是本地 git 存储库上的主分支的源分支推送，但我正在将其推送到 heroku 远程存储库上的主分支.我不知道这是否是个问题，但我认为指定这一点很重要

为了从非 master 的本地分支推送，您必须指定源分支和目标分支并用冒号分隔它们：

git push heroku <source>:<target>
