Installing Sonata Page Bundle Error with Symfony 2.8.*

Question

I am trying to install Page Bundle From Sonata Project. For some reason i cant install it because of the dependancy.

   composer require sonata-project/page-bundle
Using version ^2.3 for sonata-project/page-bundle
  Problem 1
    - sonata-project/page-bundle 2.3.9 requires sonata-project/seo-bundle ~1.1 -> no matching package found.
    - sonata-project/page-bundle 2.3.8 requires sonata-project/seo-bundle ~1.1 -> no matching package found.
    - sonata-project/page-bundle 2.3.7 requires sonata-project/seo-bundle ~1.1 -> no matching package found.
    - sonata-project/page-bundle 2.3.6 requires sonata-project/seo-bundle ~1.1 -> no matching package found.
    - sonata-project/page-bundle 2.3.5 requires sonata-project/seo-bundle ~1.1 -> no matching package found.
    - sonata-project/page-bundle 2.3.4 requires symfony/symfony >=2.2,<2.4-dev -> no matching package found.
    - sonata-project/page-bundle 2.3.3 requires symfony/symfony >=2.2,<2.4-dev -> no matching package found.
    - sonata-project/page-bundle 2.3.2 requires symfony/symfony >=2.2,<2.4-dev -> no matching package found.
    - sonata-project/page-bundle 2.3.1 requires symfony/symfony >=2.2,<2.4-dev -> no matching package found.
    - sonata-project/page-bundle 2.3.0 requires symfony/symfony >=2.2,<2.4-dev -> no matching package found.
    - Installation request for sonata-project/page-bundle ^2.3 -> satisfiable by sonata-project/page-bundle[2.3.0, 2.3.1, 2.3.2, 2.3.3, 2.3.4, 2.3.5, 2.3.6, 2.3.7, 2.3.8, 2.3.9].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

Composer.json file is ---

},
"require-dev": {

},

}

I tried few other ways to but didn't try downgrading seo-bundle and Symfony 2.8.*.

Thanks for your help in future.

Answer 1

I lowered seo-bundle to v1.1 and it worked like a charm.

I am still haveing some other problems, but atleast installation went through.
