ubuntu使用composer安装laravel

(The recommended path, not needed.)

cd /usr/local/bin

(install)

 sudo curl -s https://getcomposer.org/installer | sudo php

(Add execute permissions.)

sudo chmod a+x composer.phar

(This step is not necessary. If needed, you can use this script to update Composer.)

sudo composer.phar self-update

要有这一步，否则不能直接使用composer命令

进入到www目录

composer create-project laravel/laravel --prefer-dist
