一、在 Windows 中，你需要下载并运行 Composer-Setup.exe。
二、安装composer后，更新镜像为国内镜像

D:\>cd wamp
D:\wamp>cd www
D:\wamp\www>composer config -g repo.packagist composer https://packagist.phpcomp
oser.com（更新镜像为国内）
You are running composer with xdebug enabled. This has a major impact on runtime
performance. See https://getcomposer.org/xdebug（提示php.ini中xdebug需关闭）
