hahadeMacBook-Air:unzip v1.9.16.zip 

hahadeMacBook-Air:cd swoole-src-1.9.16/

hahadeMacBook-Air:/Applications/xampp/xamppfiles/bin/phpsize

hahadeMacBook-Air: ./configure --with-php-config=/Applications/xampp/xamppfiles/bin/php-config

hahadeMacBook-Air:make install

hahadeMacBook-Air:chmod -R 777 /Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/

hahadeMacBook-Air:make install

sudo vi /Applications/XAMPP/xamppfiles/etc/php.ini

然后修改php.ini（增加：extension=swoole.so），重启xampp服务就可以了。
