Exception 运行php artisan超时

我继承了一个Laravel4.2项目，正在进行一些清理

当我运行

php artisan

时，我得到以下结果：

[Symfony\Component\Process\Exception\ProcessTimedOutException] 
The process "php artisan clear-compiled" exceeded the timeout of 300 seconds.

我试图增加超时时间，但最终还是抛出了相同的异常

当我试图在本地和我的VM（宅地）中运行任何和所有

artisan

命令时，就会发生这种情况

运行

composer install-o-vvv

会在超时发生后显示以下堆栈跟踪（在

php artisan clear compiled

过程结束时）：

你知道这是什么原因吗？我看到的唯一信息是增加Composer的超时时间，但到目前为止，这对我来说还不起作用。

试试这个

php artisan something:test--timeout=0

如果这不起作用，请尝试删除供应商文件夹并运行
