基于这篇文章：https://mattstauffer.co/blog/installing-a-laravel-app-on-heroku
我试图将我的应用程序部署到Heroku但是当我执行推送时出现此错误：
remote: -----> Preparing runtime environment...
remote: ln: failed to create symbolic link ‘./heroku-hhvm-apache2’: File exists
remote: ln: failed to create symbolic link ‘./heroku-hhvm-nginx’: File exists
remote: ln: failed to create symbolic link ‘./heroku-php-apache2’: File exists
remote: ln: failed to create symbolic link ‘./heroku-php-nginx’: File exists
remote:

remote:
remote: ! Push rejected to studapp-stage.
remote:
To https://git.heroku.com/studapp-stage.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/studapp-stage.git'
我在Heroku上做了这个改变：
heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-php
有人可以帮助我吗？
提前致谢！
