安装laravel之前先安装composer
使用 curl 指令下载：
curl -sS https://getcomposer.org/installer | php
或是沒有安裝 curl ，也可以用 php 指令下载：
php -r "readfile('https://getcomposer.org/installer');" | php
当你下载了 composer.phar 后，可以将它放在目录中，但每次当你建立新目录时，你必須再复制一个副本到新目录中，这样比较麻烦。所以最佳做法是将它放到 usr/local/bin 目录中中，成为全域指令。 mv composer.phar /usr/local/bin/composer
之后会在当前文件夹产生composer.phar把他放进 /usr/local/bin/composer
在～/.bash_profile把/usr/local/bin添加到环境变量
vi ~/.bash_profile
exportPATH=/usr/local/bin:$PATH使用composer 安装 laravel
输入composer global require "laravel/installer=~1.1"命令查看
composer global require "laravel/installer=~1.1"
Changed current directory to /Users/yangyanqing/.composer
./composer.json has been created

new Create a new Laravel application.
1、进入到设置的根目录
cd /Users/username/wwwroot
2、此时可以使用 laravel new 命令建立一份全新安装的 Laravel 应用，
例如： laravel new blog 将会在当前目录下建立一个名为 blog 的目录，
此目录里面存放着全新安装的 Laravel 相关代码，
此方法跟其他方法不一样的地方在于会提前安装好所有相关代码，
不需要再通过 composer install 安装相关依赖，速度会快许多。
laravel new blog
或者
通过 Composer Create-Project，你一样可以通过 Composer 在命令行执行 create-project 来安装 Laravel：
composer create-project laravel/laravel --prefer-dist
3、打开浏览器： http://localhost/blog/publi
如果报错，需要给权限
chmod -R -777 blog
