Symfony 2：缓存清除时出错

Question

I have an error when i execute this command :

php app/console cache:clear --env=prod && php app/console cache:clear --env=dev && php app/console assets:install --symlink && php app/console assetic:dump

The error is :

[Symfony\Component\Debug\Exception\ContextErrorException] Catchable Fatal Error: Argument 1 passed to Sonata\AdminBundle\Security\Handler\RoleSecurityHandler::__construct() must implement interface Symfony\Component\Security\Core\SecurityContextInter face, null given, called in /opt/preprod/app/cache/pro_/ap_ProdProjectContainer.php on line 1923 and defined

Can you help i dont really know how to fix this

EDIT

I tried to backup

composer.lock

and

vendor

directory (and then delete them). Then i deleted mannually the cache. Then i made a composer install but the error is back when i made the composer install.

Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache



  [Symfony\Component\Debug\Exception\ContextErrorException]

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-install-cmd event terminated with an exception


  [RuntimeException]
  An error occurred when executing the "'cache:clear --no-warmup'" command.

php app/check.php give me everything is ok

So i dont find the way to solve this

Answer 1

What version of Symfony are you using? I would guess 2.8 or 3.0 since it looks like the version of SonataAdminBundle is not compatible with your Symfony version.
