Symfony2和作曲家问题："Could not parse version constraint composer.phar..."

Question

所以我在Symfony2上安装奏鸣曲管理包后，试图让作曲家再次工作时遇到了问题。当使用命令php composer.phar ....时，我得到以下错误消息:[UnexpectedValueException] Could not parse version constraint composer.phar: Invalid version string "composer.phar"

不管我对composer做了什么操作，它总是会产生这个错误。一个例外是php composer.phar require --no-update sonata-project/media-bundle说它更新了composer。Json，没有错误信息，但实际上没有安装任何东西。

到目前为止，我刚刚删除并重新安装了composer。请使用更新版本。我在Mac OS 10.7.5上运行Symfony 2.2.1-dev，使用MAMP和PHP 5.4.4。不确定这是否相关，但我也不能使用php app/console cache:clear清除缓存了。我必须通过Finder删除缓存。

这是我的作曲家。Json文件:

任何帮助/建议将是伟大的:)

看起来你的编写器文件中有一些拼写错误。

将"php": "composer.phar"替换为"php": ">=5.3.3"，并在文件末尾添加缺失的右括号:
