Linux 平台可以使用以下命令来安装:
php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"
php composer-setup.php
移动 composer.phar,这样 composer 就可以进行全局调用:
mv composer.phar /usr/local/bin/composer
切换为国内镜像:
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
更新 composer:
composer selfupdate
