Symfony2和作曲家问题：“无法解析版本约束composer.phar ...”

Question

因此，我在安装Symphony 2上的Sonata Admin Bundle之后尝试让作曲家再次工作时出现问题。当使用命令php composer.phar ....时，我收到以下错误消息：[UnexpectedValueException] Could not parse version constraint composer.phar: Invalid version string "composer.phar"

无论我使用composer做什么操作，它总是会产生该错误。那么，有一个例外是php composer.phar require --no-update sonata-project/media-bundle表示它更新了composer.json而没有错误消息，但实际上并没有安装任何东西。

到目前为止，我刚刚删除并重新安装了更新版本的composer.phar。我使用MAMP和PHP 5.4.4在Mac OS 10.7.5上运行Symfony 2.2.1-dev。不知道这是否相关，但我也无法使用php app/console cache:clear清除缓存。我必须通过Finder删除缓存。

这是我的composer.json文件，以防万一：

任何帮助/意见将是巨大的:)

看起来你有你的作曲文件中的一些错别字。

更换"php": "composer.phar"与"php": ">=5.3.3"并添加缺少的结束括号在文件的结尾：

    "description": "The \"Symfony Standard Edition\" distribution", 
    "autoload": {
