Answer 1

If it is blocked, you can install it by overcoming the wall, or use domestic mirroring.
First make sure php is installed, then follow the steps below.

//下载安装脚本 － composer-setup.php － 到当前目录
php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"
//执行安装过程。
php composer-setup.php
//删除安装脚本
php -r "unlink('composer-setup.php');"
