关于bower

Bower is a package manager for the web. It offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat.

1. 包管理软件，用于前端
2. 可以用命令行安装js，如同我们用apt-get install软件一样

安装bower

这里依赖于node以及Npm，所以我们需要安装nodejs，具体可以参见nodejs官网，不过如果是同Mac os或者是Ubuntu的话，可以用类似于

brew install npm

npm install -g bower

安装js包

创建一个简单的配置文件.bowerrc用于配置Bower安装路径

{
      "directory": "public/"
}

bower install angularjs

$ bower install angularjs
bower cached        git://github.com/angular/angularjs.org.git#58ef7908d9
bower validate      58ef7908d9 against git://github.com/angular/angularjs.org.git#*

如果要安装指定版本就是

bower install <name>=<package>#<version>

例如

bower install jquery#1.4
