SonataAdminBundle与Symfony~2.4 - 如何安装?

I just set up a new Symfony 2.4 project and try to install the SonataAdminBundle (instruction), but I get errors again.

History:

# install symfony (demo works!)
composer create-project symfony/framework-standard-edition ./ 2.4.*

# install admin bundle (instruction above)
composer require sonata-project/admin-bundle
-> version: dev-master

# install DoctrineORMAdminBundle (FAILS!)
composer require sonata-project/doctrine-orm-admin-bundle
-> version: dev-master

Well, I failed on step 1.2, error:

Please provide a version constraint for the sonata-project/doctrine-orm-admin-bundle requirement: dev-master
./composer.json has been updated
Loading composer repositories with package information

  [Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException]
  The service "sonata.admin.builder.orm_datagrid" has a dependency on a non-existent service "sonata.admin.builder.filter.factory".

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

  An error occurred when executing the ""cache:clear --no-warmup"" command.

require [--dev] [--prefer-source] [--prefer-dist] [--no-progress] [--no-update] [packages1] ... [packagesN]

Interesting line:

The service "sonata.admin.builder.orm_datagrid" has a dependency on a non-existent service "sonata.admin.builder.filter.factory".

Does anyone know what to do? Thanks a lot in advance!

You have to register both the SonataAdminBundle and SonataDoctrineOrmAdminBundle. It looks like you forgot to activate SonataAdminBundle.
