Heroku doesn't recognize my Laravel app as PHP app, and does not do composer install

问题

I'm trying to publish my Laravel app on Heroku. I have excluded the composer.lock file from .gitignore, and created a Procfile containing

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

I created my app with

heroku create myapp;
git push heroku master;

Then I get the following output:

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

If I browse to my app, however I get an application error. When I look to my logs, it says

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

I suspect that somehow, Heroku didn't do composer install, as it's not in my git output, and maybe it didn't even recognize that my app is an PHP app? To be sure, I also included an empty index.php file in my root. Didn't help.

What am I missing here?

回答1:

I believe I found it. Should better read the lines ("Node.js app detected"). Solved by firing this command :

heroku config:add BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-php

and pushing again

回答2:

Haha, just simply drop the package.json in your laravel project. And then Heroku will detect your app as a php project.

回答3:

Be sure to include the trailing slash on public: public/. This was my issue - I am using Laravel and got a Image source not readable and NotReadableException in AbstractDecoder.php line 302: because it thought at AbstractDecoder->init('/app/public') in AbstractDriver.php line 64 was a file, not a folder.
