When you clone the project and try to install vendors you get this error by default:

- doctrine/phpcr-bundle 1.0.0 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
- symfony-cmf/menu-bundle 1.0.0 requires doctrine/phpcr-bundle 1.0.* -> satisfiable by doctrine/phpcr-bundle[1.0.0].
- Installation request for symfony-cmf/menu-bundle 1.0.* -> satisfiable by symfony-cmf/menu-bundle[1.0.0].

I assume that this is a minimum stability issue or something like that but it would bi nice to clone a project and run it without need to change composer.json before that (I know that this is not a Sylius related problem but developers will get this error).

The way I avoided this issue is that I removed the symfony-cmf components (all of them) from composer.json and added just these two:

"knplabs/knp-menu-bundle": "2.0.@dev",
"knplabs/knp-menu": "2.0.@dev"
