未捕获的 ReflectionException：类日志(log)不存在 Laravel 5.2

I am currently trying to clone an existing project of mine from github. After clone I run composer install during the process I receive the following error:

Uncaught ReflectionException: Class log does not exist

I am running Laravel 5.2 on Centos 7.

我看到过以下提到:

• Removing spaces within the .env file.
• 删除供应商目录&amp；重新安装
• Removing certain packages required in composer.json

I have:

• Replaced my .env with the example.env to avoid any custom config errors.
• 我已删除&amp；重新克隆了回购协议.
• I have used the default composer.json shipped with Laravel to see if that makes a difference.

以上这些都没有给我带来任何快乐.我还在另一台机器上设置了相同的环境，应用程序运行良好.这里唯一的区别是机器(工作)不是从git克隆的——它是最初的构建环境.

The stack trace I am receiving:

PHP Fatal error:  Uncaught ReflectionException: Class log does not exist in /var/www/html/Acme/vendor/laravel/framework/src/Illuminate/Container/Container.php:736

任何帮助都将不胜感激.提前谢谢您.
