Uncaught ReflectionException:类日志不存在于/vender/laravel/framewor

我的Laravel 5.2运行良好，我很高兴。

然后我执行：

 php artisan config:cache

我的日子变得更黑暗

我收到这个消息：

我真的不知道如何调试它，

我试着删除我上次做的任何事情。有人说它是一个.env文件，里面有空格，但在我的情况下不是，所以基本上，我不知道如何调试它

我试过

composer dump-autoload

我试图删除供应商文件夹

所有php artisan命令都失败。

这种情况似乎发生在很多人身上，但原因总是不同的，很难调试。

任何帮助都将不胜感激！

编辑1:我可以恢复我的网站删除的功能版本

bootstrap/cache/config.php

在失败之前，我还做了一个php手工配置：缓存

以及恢复以前版本的

    bootstrap/cache/services.php

但我想使用这些命令，因为它们在生产中有很大的不同！
