Bower 是由 Twitter 推出的前端包管理工具，它类似于 Java 中的 Maven 对 jar 包的管理一样，Bower 是来管理 js、css 等前端包之间的依赖关系。
安装
因为是基于 Node，所以需要先安装 Node 以及 Npm。然后全局安装 Bower：
$ npm install bower -g
使用
初始化
$ bower init
? name (bower) bower-demo ? description a demo of bower ? main file ? what types of modules does this package expose? ? keywords bower ? authors (Jay <jay.li@baichanghui.com>) ? license (MIT) ? homepage index.html ? set currently installed components as dependencies? (Y/n) ...
这样它会自动生成一个 bower.json 的文件，里面描述了相关的项目信息和依赖信息：
{ "name": "bower-demo", "authors": [ "Jay <jay.li@baichanghui.com>"
], "description": "a demo of bower", "main": "", "moduleType": [], "keywords": [ "bower"
], "license": "MIT", "homepage": "index.html", "ignore": [ "**/.*", "node_modules", "bower_components", "test", "tests"
]
}安装依赖
