composer 安装yii2错误处理

按照  yii2 手册用composer安装,前提是安装好composer

composer globalrequire
"fxp/composer-asset-plugin:~1.0.0"
composer create-project--prefer-dist yiisoft/yii2-app-basic
basic
但是安装到第一步的时候就报错了,报错内容如下

[ErrorException]

  Declaration of Fxp\Composer\AssetPlugin\Repository\AbstractAssetsRepository

  ::whatProvides() should be compatible with Composer\Repository\ComposerRepo

  sitory::whatProvides(Composer\DependencyResolver\Pool $pool, $name, $bypass

  Filters = false)

也就是fxp插件不兼容错误

那么第一步可以修改下版本,因为和版本有关系

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