我正在尝试将我的php应用程序从github部署到heroku，但无法正常工作。我有将PHP应用程序部署到heroku的经验，但是由于某种原因，这次我遇到了麻烦。
这就是我所做的。
git push heroku master 我的目录包含以下文件:
home.html
index.php
index.css
这是我的
index.php:Push rejected, failed to detect set buildpack heroku/php这是我在第5步后得到的:

最佳答案
就我而言，我需要在git文件夹所在的目录中有一个 composer.json 文件。在尝试执行git push heroku master之前，还请确保已在提交中包含json文件。
我的composer.json文件仅包含此内容，因此它是有效的json。
