2.dos命令符cd到ionic_app文件夹内
3.使用命令新建app ionic start ionic_demo3 sidemenu
过了很久就很长串报错信息

我看到有个警告说没有安装 Git CLI ，然后去官网看了安装方法
npm install git-cli
然后又是一堆错误，今天一天都在搞这个，头都大了，求大神帮忙解答下！万分感谢，跪谢
具体疑问点：
1.npm我已经装了，为什么还有npm install
2.疑问2背景：最开始我使用Ionic看的是 这个网站（http://www.ionic.wang/js_doc-...），点击导航上的[赞助教程]到了个，phonegap100的网站，然后看里面的教程看了半天，感觉被带歪了的感觉，研究了好久的phonegap，感觉不对劲，今天才转身重来
疑问2：使用Ionic开发app，也需要安装Android sdk吗？也需要安装什么ant吗？
提此问题的主要目的就是，我想能够正常的使用Ionic创建官网实例，从而达到自己使用Ionic做自己的app
不知道是我的方法有问题还是怎么了，一直没有进度，希望能有人指导下，谢谢了
问题目前已经解决，大致原因可能是：
解决方法，使用国内镜像进行安装，具体安装方法：http://www.cnblogs.com/fighxp...
ionic start myApp tabs后，还需切换到应用文件夹内，执行ionic serve才 www文件夹内才会生成对应文件，且会自动打开电脑默认浏览器进行预览
