通过安装Composer方式安装Yii

如果还没有安装 Composer，你可以按 getcomposer.org 中的方法安装。 在 Linux 和 Mac OS X 中，你可以运行如下命令：

curl -sS https://getcomposer.org/installer | php

mv composer.phar /usr/local/bin/composer

步骤：

一、打开终端

二、安装composer：

1、终端输入：curl -sS https://getcomposer.org/installer | php

composer安装成功

2、终端输入：mv composer.phar /usr/local/bin/composer

将composer.phar移动到 /usr/local/bin/composer支持全局访问composer命令

3、验证方法：(注意：需要有访问权限，否则会提示没有权限访问)

输入：composer -v

三、安装Yii2

Composer 安装后，切换到一个可通过 Web 访问的目录，执行如下命令即可安装 Yii ：

composer global require "fxp/composer-asset-plugin:^1.2.0"

composer create-project --prefer-dist yiisoft/yii2-app-basic basic

第一条命令安装 Composer asset plugin， 它是通过 Composer 管理 bower 和 npm 包所必须的，此命令全局生效，一劳永逸。

第二条命令会将 Yii 安装在名为 basic 的目录中。如果你想使用其它目录名称，你可以选择其他目录名称。

1、终端输入：composer global require "fxp/composer-asset-plugin:^1.2.0"

如果你没有安装Gii该过程会提示你是否安装，安装即可（以下个人项目名称cqy，当然也可以修改成自己想要的项目名称）

2、终端输入：composer create-project --prefer-dist yiisoft/yii2-app-basic cqy

如果出现以下提示：

说明你权限不够，输入：sudo -s，提供root权限

有了权限之后重新输入命令，当进行到一半的时候发现需要token

token命令的话需要Github账号来获取
3、获取token
在使用github获取数据的时候，需要注册一个github账户
在账户 Account -->Setting 点击后页面刷新后， 点击 Personal access tokens， 点击Generate new Token按钮 生成token
获取到token后输入即可继续安装，如下：
