Symfony 2 upgrade to 2.1: LogicException: Containe

Question

Just upgrading to Symfony 2.1. Been following the guides:

• https://github.com/symfony/symfony-standard/blob/master/UPGRADE.md
• https://github.com/symfony/symfony/blob/master/UPGRADE-2.1.md

Everything seemed to go well, but now I keep getting the following exception

LogicException: Container extension "security" is not registered

I have compared my settings to the lastest available download of Symfony 2.1 and I can't see why the security extension is not registered. Can anyone help me out?

Answer 1

It seems that the cached container configuration is at fault. I resolved this issue by running the following:

rm app/bootstrap.php.cache
composer install

Answer 2

it seems that your depedencies are broken,

Try to update you composer, and send me back an answer if it works

php composer.phar update
