我的 php 版本是 5.4.6，下载作曲家的最后一个快照后，我无法创建新项目并更新作曲家版本。

php composer.phar create-project --stability=dev yiisoft/yii2-app-basic basic

Warning: This development build of composer is over 30 days old. It is recommended to update it by running "composer.phar self-update" to get the latest version.

php composer.phar 自我更新

【解决方案1】：

Yii2 安装

(1) 首先安装 Composer (LINUX)：

本地：

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

php -r "读取文件('https://getcomposer.org/installer');" | php

curl -sS https://getcomposer.org/installer | php -- --install-dir=bin

或

全球：

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

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

(1) 首先安装 Composer (WINDOWS)：

C:\Users\username>cd C:\bin

C:\bin>php -r "readfile('https://getcomposer.org/installer');" | php

注意：如果由于readfile导致上述失败，请使用http url或在php.ini中启用php_openssl.dll

C:\bin>echo @php "%~dp0composer.phar" %>composer.bat*

C:\Users\username>作曲家-V 作曲家版本 27d8904

(2) Yii2 框架在线下载：

基本应用： php composer.phar create-project yiisoft/yii2-app-basic basic 2.0.0-beta

高级应用： php composer.phar create-project yiisoft/yii2-app-advanced advanced 2.0.0-beta
