我试着在heroku上部署我的简单django项目，但是我不知道如何解决这个问题
这是一个

如果有人能帮助我，或者推荐其他免费部署django项目的方法，那就太好了

整个回溯过程都在括号内：() is not available for this stack。这是当你请求一个不可用的Python运行时显示的消息。在这种情况下，看起来你的runtime.txt甚至因为一个意外的编码而不能被读取。
删除它，然后创建一个新文件，其中包含类似于

python-3.10.2

请确定它是UTF-8编码、认可并重新部署。
目前，这些是当前支持的Python版本，但列表会随着新版本的发布而变化：

python-3.10.2
python-3.9.10
python-3.8.12
python-3.7.12

当我在Heroku上部署Django应用程序的时候，我遇到了同样的问题。这个问题是因为编码错误。Heroku希望文件用UTF-8保存，但是我意识到我的文件是用UTF-16 le保存的。
因此，如果您正在使用vscode，那么我建议您检查vscode底部的运行时文件的编码。
如果你点击utf-8，你会看到用不同的编码保存文件的选项。否则你也可以用记事本保存文件。记事本使用的默认编码是utf-8
那肯定行。
如果这不能解决问题，请检查其他文件编码

非常简单，只需删除runtimeidertxt，并推动代码，这对我来说是有效的。谢谢
