Why does symfony 2.4.1 give errors when installing ipp/content-bundle?

Question

symfony

When installing ipp/content-bundle it gives errors. What to do?
I understand the version of the symphony does not match? what can be done?
composer.json

....
"minimum-stability": "dev",
    "autoload": {
        "psr-0": {
            "": "src/",
            "Application": "app/"
        }
    },
    "require": {
        "php": ">=5.3.3",
        "symfony/symfony": "~2.4",
        "doctrine/orm": "~2.2,>=2.2.3",
        "doctrine/doctrine-bundle": "~1.2",
        "twig/extensions": "~1.0",

Answer 1

It seems to be in conflict with the version of the framework. You have installed 2.4.* Try to install version 2.3.* It should be understood that not all bundles and not all their versions are suitable for each other. The problem is most likely in compatibility, which is why the installer does not give you a go.
