Yii2.0 安装无法使用 composer

Question

composer create-project --prefer-dist yiisoft/yii2-app-basic basic
以下是上述命令的输出

Installing yiisoft/yii2-app-basic (2.0.6)  
  - Installing yiisoft/yii2-app-basic (2.0.6)  
    Loading from cache  
Created project in basic 
Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

 Problem 1
- yiisoft/yii2 2.0.6 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stable -> no matching package found.
- yiisoft/yii2 2.0.5 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stable -> no matching package found.
- Installation request for yiisoft/yii2 >=2.0.5 -> satisfiable by yiisoft/yii2[2.0.5, 2.0.6].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

Answer 1

请参考installation guide。看来您缺少资产插件：

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

Answer 2

你应该在运行之前先运行composer clear-cache

composer global require "fxp/composer-asset-plugin:~1.1.1" 

这对我有用。
