每个项目 Mac OS X 的 Composer 内存不足

我昨天尝试使用Composer在我的Laravel 4项目之一上安装，我不记得确切的事件链，但它没有成功安装。从那以后，我一直收到Composer耗尽内存的错误 - .aws/aws-sdk-phpFatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 32 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52

我将php.ini增加到-1，这仍然发生在我的开发和生产环境中（生产是Cent OS 6）。如果我在运行时通过 CLI 增加安装，安装将成功完成，但这需要很长时间。memory_limitmemory_limitcomposer_update

是否有某种缓存需要清除以防止 Composer 内存不足？我有一种感觉，每次运行 Composer 更新时，它仍在尝试安装 AWS 开发工具包。
