推荐答案
阅读此文档，它将向您解释要做什么.
https://devcenter.heroku.com/articles/buildpacks
Read this doc which will explain to you what to do.
https://devcenter.heroku.com/articles/buildpacks
您可以通过设置 buildpack 值来更改应用程序使用的 buildpack.
下次推送应用程序时，将使用新的 buildpack.
$ heroku buildpacks:set heroku/php
Buildpack 套装.random-app-1234 的下一个版本将使用 heroku/php.
运行 git push heroku master 以使用此构建包创建新版本.
Buildpack set. Next release on random-app-1234 will use heroku/php.
Run git push heroku master to create a new release using this buildpack.
这就是为什么它不适合你，因为你没有设置它.
This is whay its not working for you since you did not set it up.
... 下次推送应用程序时，将使用新的 buildpack.
您还可以在应用创建过程中指定构建包:
$ heroku create myapp --buildpack heroku/python
