将 symfony 2.0 升级到 2.1 加载 symfony 包时出错

Question

我在运行 composer.phar 安装时出现此错误 :

[RuntimeException] Could not load package symfony/framework-standard-edition in http://packagist.org: [UnexpectedValueException] Could not parse version constraint ^2.4.8: Invalid version string "^2.4.8"

我使用 composer 1.0.0-alpha7，我正在将我的 symfony 项目 2.0 升级到 2.1

这是我的 composer.json 文件：

{ "name": "symfony/framework-standard-edition", "license": "MIT", "type": "project", "description": "The \"Symfony Standard Edition\" distribution",

"autoload": {
    "psr-0": { "": "src/" }
},

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.1.*"
},
"scripts": {
    "post-install-cmd": [
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap",
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache",
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installAssets",
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installRequirementsFile"
    ],
    "post-update-cmd": [
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap",
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache",
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installAssets",
        "Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installRequirementsFile"
    ]
},
"minimum-stability": "dev",
"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "symfony-assets-install":"symlink"
}

}

你有想法吗？

Answer 1

您必须运行 composer selfupdate，因为您使用的 Composer 版本尚不支持版本限制中的 ^ 运算符。

Answer 2

好的，我发现我的问题了：我只是删除了我的 composer.json

的 "minimum-stability": "dev"
