Laravel 5.2 - php 工匠失败 - 进程已发出信号“5”信号

所以我正在尝试在我的Mac OSX 10.10上安装一个laravel应用程序，当运行作曲家安装时，它会进入后脚本"清除编译/优化"并失败并出现以下错误：

> post-install-cmd: php artisan clear-compiled

  [Symfony'Component'Process'Exception'RuntimeException]
  The process has been signaled with signal "5".

几乎找不到关于此错误的解释方式，我发现的几个地方提供了诸如更新SVN或git之类的东西以及其他一些看似无关的解决方案。知道是什么原因造成的吗？
