安装 Symfony 2.2 时遇到问题。*

Question

我正在尝试安装 symfony 2.2.* 但它显示此错误

"require": {
    "php": ">=5.3.3",

     "symfony/symfony": "2.2.*",
    "sonata-project/admin-bundle": "2.3.*@dev",
    "sonata-project/cache-bundle": "dev-master",
    "sonata-project/block-bundle": "2.2.*@dev",
    "sonata-project/jquery-bundle": "1.10.*@dev",
    "sonata-project/doctrine-orm-admin-bundle" : "2.3.*@dev",
    "sonata-project/core-bundle": "2.2.*",


    "doctrine/orm": "~2.2,>=2.2.3",
    "doctrine/doctrine-bundle": "1.2.*",
    "twig/extensions": "1.0.*",
    "symfony/assetic-bundle": "2.1.*",
    "symfony/swiftmailer-bundle": "2.2.*",
    "symfony/monolog-bundle": "2.2.*",
    "sensio/distribution-bundle": "2.2.*",
    "sensio/framework-extra-bundle": "2.2.*",
    "sensio/generator-bundle": "2.3.*@dev",

这是出现的错误。 我猜它会按顺序检查每个版本，但最后它没有安装任何东西。

我已经多次更改版本，但都没有解决。

Answer 1

不再支持 Symfony2.2.*。 http://symfony.com/roadmap?version=2.2

尝试更改版本说明或按照说明进行操作

• http://symfony.com/doc/current/book/installation.html
• http://sonata-project.org/bundles/admin/2-2/doc/index.html

Answer 2

您的问题来自奏鸣曲库。您尝试安装"sonata-project/admin-bundle": "2.3.*@dev"，而根据packagist，此版本仅与 Symfony >= 2.3 兼容。其他奏鸣曲库也是如此。

所以，你有两个解决方案：

• 将奏鸣曲库降级到与 Symfony 2.2.* 兼容的 2.2.*
• 将 Symfony 升级到 2.3.* 或更高版本

基本上，在需要库之前，您需要检查http://packagist.org，如果您指定的版本与您的其他包兼容。
