我继承了一个 Laravel 4.2 项目并正在执行一些清理工作。
当我跑步时，php artisan我得到了这个：
[Symfony\Component\Process\Exception\ProcessTimedOutException]
The process "php artisan clear-compiled" exceeded the timeout of 300 seconds.
我试图增加超时，但它最终仍然会抛出相同的异常。
当我尝试artisan在本地和我的 VM（Homestead）中运行任何和所有命令时，就会发生这种情况。
超时发生后运行composer install -o -vvv显示以下堆栈跟踪（在 期间结束php artisan clear-compiled）：

关于可能导致这种情况的任何想法？我看到的唯一信息是增加 Composer 的超时时间，但到目前为止这对我没有用。
