我正在尝试通过composer安装Yii2:

composer global require "fxp/composer-asset-plugin:~1.1.1"
composer create-project --prefer-dist yiisoft/yii2-app-basic basic

〜/ .composer/composer.json

{
    "require": {
    "fxp/composer-asset-plugin": "~1.1.1"
    }
}

结果:

Problem 1
- yiisoft/yii2 2.0.x-dev requires bower-asset/jquery 2.1.*@stable | 1.11.*@stable -> no matching package found.
- yiisoft/yii2 dev-master requires bower-asset/jquery 2.1.*@stable | 1.11.*@stable -> no matching package found.
- 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 …

是否可以在连接查询中添加条件？

例如我想构建下一个查询：

select * from clients
left join comments on comments.client_id = clients.id and comments.type = 1

Client.joins(:comments).all 只生成：

select * from clients
left join comments on comments.client_id = clients.id

附注。Client.joins("LEFT JOIN comments on comments.client_id = clients.id and comment.type = 1")不是很好
