在heroku上部署页面时出现的Python版本问题

在heroku上部署页面时：

wumengtiandeMacBook-Pro:web wumengtian$ git push heroku master

然后：

remote: Compressing source files... done.
remote: Building source:
remote: 
remote: -----> Python app detected
remote: -----> Installing Python-3.6.2
remote:  !     Requested runtime (Python-3.6.2) is not available for this stack (heroku-16).
remote:  !     Aborting.  More info: https://devcenter.heroku.com/articles/python-support
remote:  !     Push rejected, failed to compile Python app.
remote: 
remote:  !     Push failed
remote: Verifying deploy...
remote: 
remote: !    Push rejected to safe-peak-44258.

所以我搜索 它显示以下图像：

问题是否真的取决于版本？还是别的什么？谢谢大家!

请尝试删除runtime.txt并重新部署。 我也遇到了同样的问题，就在之前，它对我起了作用
