在服务器上部署 Laravel 工程遇到 ReflectionException 求助

用 Laravel 框架写了一个工程，已经在本机测试好了，准备部署到一台外网服务器（阿里云的）。

目前这台服务器操作系统是 Ubuntu 12.04，装了 PHP 5.6.18，根据 JellyBool 的帖子进行了 Nginx 配置，访问后是 Laravel 的出错页面：

看了一下 larval.log 中的 log，内容如下：

执行过 composer dump-autoload，提示一行绿字 Generating autoload files，没有成功失败提示。

另外，php 没有启用 openssl，尝试启用但是遇到一些麻烦，不知道目前是否有必要，暂时没有启用。
