Deploy Symfony2 application to prod environment causes post-install-cmd exception - php

Question

I have read Symfony2 docs for How to deploy a Symfony2 application but I'm having some issues|warnings. As said here the first command I run is this one:
composer install --no-dev --optimize-autoloader
That command uninstall|erase Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle and I got this error at console:
Generating optimized autoload files
PHP Fatal error: Class 'Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle' not found in /var/www/sis-php-source/app/AppKernel.php on line 40
PHP Stack trace:

What I'm doing wrong? Is not that the right way to deploy a Symfony2 application? How I can fix that issue?

Answer 1

Have you read the info box on the documentation page?
If you get a "class not found" error during this step, you may need to
run export SYMFONY_ENV=prod before running this command so that the
post-install-cmd scripts run in the prod environment.
