Heroku rejects push because it cannot clear the cache Symfony3

Question

Working all day to deploy my application to heroku, but every time it throws out an error. And i am all out of clues, and have a very angry customer.

When i try to add my project to heroku with the command git push heroku master every thing is fine till the cache needs to be cleared.

Updating the "app/config/parameters.yml" file
remote:        > Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap
remote:        > Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache
remote:        Could not open input file: app/console
remote:        Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the symfony-scripts event terminated with an exception
remote:
remote:
remote:          [RuntimeException]
remote:          An error occurred when executing the "'cache:clear --no-warmup'" command:
remote:          Could not open input file: app/console
remote:          .

You would think, it's the same as this git issue

Also a know problem, that i am using a wrong type of mapping.

But i think it's fine.

I updated my composer and cleared the cache of my composer

And when i clear the cache with p hp bin/console cache:clear everything is fine!

I followed this tutorial And got some side information from the symfony site.

Also found this stack - with the explanation what is going on, but this is still not solving my problem.

Maybe it's somewhere in my composer file, or my git ignore. But honestely, i have no idea anymore.

Answer 1

You upgraded a Symfony 2 app to 3.

But it is not sufficient to change the requirements in composer.json .

The structure changed, so you need to first create a new fresh app with Symfony 3 and then move the old Symfony 2 app to the fresh Symfony 3 one, bundle by bundle, composer requirement by composer requirement.

This way you'll be sure your app will work well on version 3.

If you try to simply upgrade the requirements from a Symfony 2 app, then you'll create a lot of bugs, as the scripts changed, the structure changed, the requirements changed...

The only safe way is to start a new Symfony 3 project and then port the old Symfony 2 into it.

Answer 2

The solution that worked for me. New Symfony 3 installation: Could not open input file: app/console in composer install

EXPLANATION:

That's what I guess. When you push your code to Heroku, the platform compiles your project files on the /tmp dir. What happens if you don't have a var dir when Heroku compiles your code? What happens is that Symfony creates a new one:

vendor/sensio/distribution-bundle/Composer/ScriptHandler.php:462

protected static function useNewDirectoryStructure(array $options)
{
    return isset($options['symfony-var-dir']) && is_dir($options['symfony-var-dir']);
}

Then when Heroku moves your new code to the /app dir, the Symfony configuration still points to the old placement /tmp , but files placed at /tmp are now deleted!

Answer 3

I took a look at your github repository. Seems like it's in the Symfony3 format, so I'm not certain what is going on. I want to try something, but I'm not sure if it will work.

Try editing your composer.json file manually to add the bin directory:

"config": {
        "bin-dir": "bin",
        "platform": {
            "php": "5.5.9"
        }
},

Then see if that fixes the problem.

EDIT #2

Now revert those changes and try this:

"extra": {
    "symfony-app-dir": "bin",
    "symfony-bin-dir": "bin",
    "symfony-var-dir": "var",

In other words change the app directory to "bin".
