首先安裝composer
apt-get install composer
修改默認的鏡像地址
composer config -g repo.packgist composer https://mirrors.aliyun.com/composer
創建項目
composer create-project topthink/think [project_name]
如果出現：Your requirements could not be resolved to an installable set of packages.
解決方法如下：
composer install --ignore-platform-reqs
或者
composer update --ignore-platform-reqs
後續再補。。。
