折腾：
【未解决】Mac中安装和使用composer安装php的库php-html-parser
期间，去安装php的库：
composer install Loading composer repositories with package information Updating dependencies (including require-dev)
然后就没输出，没反应了。
composer install Updating dependencies
json – Composer hanging while updating dependencies – Stack Overflow
去暂时把XDebug停止掉试试
/Applications/MAMP/bin/php/php7.2.1/conf/php.ini
确保关闭了xdebug：phpinfo中找不到xdebug了
结果问题依旧：
php – Slow updating of composer dependencies, despite –prefer-dist flag – Stack Overflow
# php -m | grep xdebug
空的，没有。
试试：
composer install --prefer-dist -vvv --profile

稍等一会，是有进展的：

但是后续downloading依旧很慢很慢
感觉现在问题变成了：
php的composer install期间去下载repo.packagist.org的包的速度太慢
看看是否有镜像或者代理可以缓解
composer install repo.packagist.org 太慢
composer config -g repo.packagist composer https://packagist.phpcomposer.com
然后重新试试：
composer install --prefer-dist -vvv --profile
速度就很快了：
瞬间就安装完毕了：

【总结】
此处php的composer install慢的原因：
1.首先排查的是XDebug
并不是表示你一定开启了XDebug，而是当前运行：
composer install
的命令行中，php是否加载啦XDebug
可以通过：
php -m | grep xdebug
确认没有XDebug
如果有加载，注释掉配置，比如此处的：
/Applications/MAMP/bin/php/php7.2.1/conf/php.ini
[xdebug] ; zend_extension="/Applications/MAMP/bin/php/php7.2.1/lib/php/extensions/no-debug-non-zts-20170718/xdebug.so" ; xdebug.remote_autostart=1 ; xdebug.remote_enable=1 ; xdebug.remote_host=localhost ; xdebug.remote_port=9000 ; xdebug.remote_handler=dbgp
2.如果还慢，那去加上 verbose参数：
composer install --prefer-dist -vvv --profile
这样可以看出来具体慢在哪里。
3.如果是和我一样，是慢在
Downloading http://repo.packagist.org/...
那可以通过添加镜像解决
配置全局的镜像
composer config -g repo.packagist composer https://packagist.phpcomposer.com
再去：
composer install
就很快了。此处几十秒就安装完毕了。
