Posted on Jun 08, 2017 By anchoriteFili

Composer安装

  1. 下载安装composer（终端命令） 
    ~$ curl -sS https://getcomposer.org/installer | php
或
~$ php -r "readfile('https://getcomposer.org/installer');" | php
  2. 将composer移动到bin中，终端就可以直接使用composer的命令了 
    ~$ mv composer.phar /usr/local/bin/composer

Composer使用
