安装doctrine

安装doctrine首先要安装pear，见我上一篇文章

1. 添加doctrine初始化通道

pear channel-discover pear.symfony.com//这个是doctrine所依赖的

pear channel-discover pear.doctrine-project.org

2. 安装doctrine核心包

pear install pear.doctrine-project.org/DoctrineORM

//此时会安装一下5个包

install ok: channel://pear.doctrine-project.org/DoctrineCommon-2.3.0
install ok: channel://pear.symfony.com/Console-2.4.4
install ok: channel://pear.symfony.com/Yaml-2.4.4
install ok: channel://pear.doctrine-project.org/DoctrineDBAL-2.3.4
install ok: channel://pear.doctrine-project.org/DoctrineORM-2.3.3
