1.2解决：

cd /

cd /tmp/pear

sudo chmod -R 777 install/

1.41这里的macOS_10.14.pkg，是自己mac的版本号

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

You should add "zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20160303/xdebug.so" to php.ini

---

1.5将zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20160303/xdebug.so加入t php.ini

1.6重启apache，并测试

sudo apachectl restart

PHP代码

$a = "new string";
xdebug_debug_zval('a');
