laravel突然出现[2017-10-22 09:51:01] production.ERROR: exception 'RuntimeException' with message 'Directory name must not be empty.' in F:\xiangmu\tms\vendor\symfony\finder\Iterator\RecursiveDirectoryIterator.php:54 Stack trace:错误

今天在laravel5.4开发中，突然出现这个错误，瞬间我就楞逼了

Whoops, looks like something went wrong.

what?然后去storage/logs/laravel.log看了下报错日记

什么鬼，排查了一大推问题，没发现什么错误哈。回想刚才的一幕幕，在想我肯定误加和误点了什么。查了好久，终于发现问题了。因为手误原因，把config文件拉到了app文件夹里面。哎，把他拉出来就没事了。
