我试过用pear安装代码嗅探器，但我的mac无法识别phpcs命令。

我检查了php_bin，php可执行文件就在那里。
当我运行phpc时，我得到

最佳答案
phpcs脚本应该在bin_dir中，所以在/usr/local/pear/bin/phpcs中，只需确保文件首先存在。如果没有，安装程序就出错了。
查看是否可以直接运行：php /usr/local/pear/bin/phpcs -?
如果这输出phpcs帮助，那么phpcs安装正确，问题可能是您的$path。运行echo $PATH并确保/usr/local/pear/bin显示在其中。如果不是，您可以修改路径设置，或者您可以配置PEAR将可执行脚本放置在其他地方。
例如，您的$path可能已经包含/usr/local/bin（就像我的Mac一样），因此您可以将bin_dir更改为：
pear uninstall php_codesniffer
pear config-set bin_dir /usr/local/bin
pear install php_codesniffer
现在再次尝试
phpcs命令。关于php - 多次安装和升级后，codeniffer命令无法识别，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/13180667/
