ionic是什么： Ionic(ionicframework)一款开源的Html5移动App开发框架,是AngularJS移动端解决方案,Ionic以流行的跨平台移动app开发框架phoengap为蓝本，让开发者可以通过命令行工具快速生成android ios移动app应用 phoengap是什么？ PhoneGap是一个用基于HTML，CSS和JavaScript的，创建移动跨平台移动应用程序的快速开发平台。它使开发者能够利用iPhone，Android，Palm，Symbian,WP7,WP8,Bada和Blackberry智能手机的核心功能——包括地理定位，加速器，联系人，声音和振动. 通俗的讲：ionic是一款基于angularjs的html5移动app开发框架 phonegap就是一款可以打包并且可以让js调用原生的移动app框架那我不用命令安装ionic 可以使用ionic开发app吗？答案是可以得。就可以把ionic当作一款html5 移动app框架，把phonegap/cordova 当作打包并且调用原生的框架就可以了至于：为什么ionic也可以打包，上面也说了，ionic的打包插件是基于phonegap/cordova的首先我们需要明确以下几个概念： 1.即使我们将移动端web页面做得和原生应用及其相似，在我们的页面中也无法像原生应用那样调用原生的能力
