我花了一整天的时间在我的mac El Capitan上安装pear代码嗅探器。我还从这个链接安装了codeigniter嗅探器跟随这个视频教程。现在，当我测试我的编码器代码时，我得到下面的error
amits-iMac:~ amitpatil$ phpcs --standard=Codeignitor /Applications/AMPPS/www/project/front/application/controllers/about.php

这个repo看起来很旧，它不能与我尝试过的任何PHP_CodeSniffer版本一起工作。但解决方法相对简单。src目录只需要重命名:
$ cd CodeIgniter-for-PHP_CodeSniffer
$ mv src CodeIgniter
现在它应该通过运行命令来工作:phpcs --standard=/path/to/CodeIgniter-for-PHP_CodeSniffer/CodeIgniter /path/to/code
