brew安装php7.3.11后用pecl安装xdebug
网络上听说，brew把xdebug移除了，查询一下，确实已经变成关闭的了：
brew search xdebug
No formula or cask found for "xdebug".

于是考虑使用pecl 安装xdebug，运行pecl install xdebug提示成功后，却发现这个so文件不存在，因为pecl这个目录根据就不存在，这估计是brew的失误，

从安装日志上来看，是能正常安装的，只是一个brew没有准备这个目录，另一个xdebug并不强制保证这个目录存在，最后，一路下来，白装了，那么给它补上这个目录看看如何

再重新pecl install xdebug，通过pecl list看到了xdebug了，php -i|grep xdebug也看到已经加载。
注意，因为so放到该目录会自动加载，所不要再在php.ini中手工添加zend_extension=xdebug方式加载了
