Updating symfony2 composer raise errors - symfony

Question

When I try to run command php composer.phar update it raise these error:
Your requirements could not be resolved to an installable set of packages.
Problem 1
- sonata-project/admin-bundle dev-master requires sensio/generator- bundle ~2.3 -> no matching package found.
- sonata-project/admin-bundle dev-master requires sensio/generator- bundle ~2.3 -> no matching package found.
- Installation request for sonata-project/admin-bundle dev-master -> satisfiable by sonata-project/admin-bundle[dev-master].
Here is my composer.json data:

How can I fix this composer update issue?

Answer 1

You're using an outdated version of Symfony2: 2.2. The dev-master branch of sonata-project/admin-bundle requires the ~2.3 version of sensio/generator-bundle which is not available with Symfony 2.2. You should try the 2.2.x-dev version which requires the 2.2 version of sensio/generator-bundle. So you have to edit your composer.json file and replace:
"sonata-project/admin-bundle": "dev-master",
"sonata-project/doctrine-orm-admin-bundle": "dev-master",
With:
"sonata-project/admin-bundle": "2.2.*",
"sonata-project/doctrine-orm-admin-bundle": "2.2.*",
