　　命令不多 ，简单看看，就能理解，基本上和npm类似。

二、包的安装

通常我们简单使用bower install [安装包]，但在开发中，项目要上传到版本库时，bower_components文件夹类似node_modules一样，是被忽略（ignore）。

1.初始化，生成配置未见bower.json

bower init

2.安装的软件包，要保存在bower.json的devDependencies中

bower install --save jquery@1.7.2 #@跟的是版本好，如果不跟，则软件包是最新版本

我就可以查看到bower.json中生成devDependencies

几乎和npm没什么区别

三、列出bower下载的软件包的列表

bower list

　　

四、查看包的信息

bower info jquery

　　

五、搜索包的有哪些版本

bower search bootstrap

　　

六、包的卸载

bower uninstall bootstrap
