update" to get the latest version.
解决方法：
composer selfupdate
2、错误二：
You are running composer with xdebug enabled. This has a major impact on runtime
performance. See https://getcomposer.org/xdebug
安装完成composer之后，cmd运行composer出现上述错误，需要打开PHP配置文件php.ini，找到zend_extension,讲该配置项注释掉即可解决
3、Fatal error: Call to undefined method Fxp\Composer\AssetPlugin\Package\Version\V
ersionParser::parseLinks() in C:\Documents and Settings\Administrator\Applicatio

解决方法：
删除composer资源插件，重新安装
如果还有错误，尝试全局更新 composer global update
4、如果是在使用yii框架的时候，会出现一下问题
The "yiisoft/yii2-composer" plugin requires composer-plugin-api 1.0.0, this *WIL L* break in the future and it should be fixed ASAP (require ^1.0 for example).

解决办法：
Yii2 需要 composer-plugin-api 1.0 以上的版本，运行以下命令：
composer global require "fxp/composer-asset-plugin:~1.1.1"
