Heroku不会将我的Laravel应用程序识别为PHP应用程序,也不会进行

web: vendor/bin/heroku-php-apache2 public

我创建了我的应用程序

heroku create myapp;
git push heroku master;

然后我得到以下输出：

git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree push -v --tags heroku master:master

如果我浏览到我的应用程序,但是我收到应用程序错误.
当我查看我的日志时,它说

app[web.1]: bash: vendor/bin/heroku-php-apache2: No such file or directory

我怀疑,不知何故,Heroku没有做作曲家安装,因为它不在我的git输出中,也许它甚至没有认识到我的应用程序是一个程序？
可以肯定的是,我还在root中包含了一个空的index.php文件.没有帮助.

我在这里错过了什么？
