我不明白這位作曲家的要求是什么

Question

我正在嘗試使用此composer.json使舊的php projet工作：

{
    "minimum-stability": "dev",
    "name": "symfony/framework-standard-edition",
    "description": "The \"Symfony Standard Edition\" distribution",

    },

    },
    "extra": {
        "symfony-app-dir": "app",

        "branch-alias": {
            "dev-master": "2.1-dev"
        }
    }
}

運行php composer.phar install其打印出來：

Your requirements could not be resolved to an installable set of packages.

我不明白這個錯誤。 我該怎么做才能使composer.json工作？

Answer 1

答案在錯誤消息中。 您需要Symfony版本2.2.4，而doctrine-fixtures-bundle（2.3）需要Symfony 2.3。 因此，您必須降低燈具套件版本或提高Symfony版本。 目前，您要求的版本無法一起使用。
