Laravel 5.2-php artisan失败-进程已通过信号“发出信号”；5“；

因此，我试图在Mac OSX 10.10上安装一个laravel应用程序，当运行composer install时，它会进入后期脚本“clear compiled/optimize”，并失败，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".

跟踪/BPT陷阱：5

我几乎找不到关于这个错误的解释，我找到的几个地方提供了更新SVN或git以及其他一些不相关的解决方案。你知道这是什么原因吗？

试试这个：

composer install --no-scripts

---

当然，这是可行的，因为它跳过了导致问题的post脚本……但这并没有告诉我为什么会发生这种情况，或者如何在不失败的情况下运行这些命令。您全局设置了composer，对吗？尝试“composer self update”，然后“composer install--preference dist”，避免使用脚本@Piya不是一个选项。我确实运行了这两个命令，但仍然没有用。你有调试器吗？那我就有点困惑了。因为这个问题很少见。
