您至少需要使用一个空的 composer.json 申请。

$ echo '{}' > composer.json
$ git add composer.json
$ git commit -m "add composer.json for PHP app detection"

如果您还有来自其他框架或语言的文件可以触发另一个 buildpack 将您的应用程序检测为其中一个拥有，例如可能会导致您的代码被检测到的 package.json 作为一个 Node.js 应用程序，即使它是一个 PHP 应用程序，那么你需要手动设置您的应用程序以使用此构建包：

$ heroku buildpacks:set heroku/php

这将使用正式发布的版本。使用默认值改为从 GitHub 分支：

$ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-php
