在这里以ext js 6.2.1版本为例（注：需要安装Sencha Cmd，以及下载对应的sdk）
1.创建空白项目
在命令行中输入sencha -sdk D:\Code\ext-6.2.1 generate app app D:\Code\Test
D:\ASPX\ext-6.2.1 是指sdk目录
generate app app 是创建应用，这个应用的包名是app
D:\ASPX\Test 就是所创建项目的目录了
运行一下项目，效果是这样的
2.修改app.json
{
//使用sencha -sdk sdk地址 generate app app 目标项目地址命令生成项目
//修改app.json后依次执行以下命令即可使用
//::重新生成开发环境sencha app build development
//::打包sencha app build -c

3.修改index.html
<!DOCTYPE HTML>
<html manifest=""> <head>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=10, user-scalable=yes"> <title>app</title> <script type="text/javascript">
var Ext = Ext || {}; // Ext namespace won't be defined yet... //根据theme参数切换皮肤，目前支持neptune、modern、classic三种
Ext.beforeLoad = function (tags) {
var theme = location.href.match(/theme=([\w-]+)/);
theme = (theme && theme[1]) || 'classic'; console.log('加载系统主题方案:' + theme);
Ext.manifest = theme + '.json'; };
</script> <!-- The line below must be kept intact for Sencha Cmd to build your application -->
<script id="microloader" data-app="1a948c1b-4dad-4c78-8917-615ca8bb45cf" type="text/javascript" src="bootstrap.js"></script> </head> <body></body> </html>
4.修改代码
我的需求只需要支持classic即可，所以我们修改一下代码，把classic目录中的所有文件移动到根目录即可。需要移动的文件就那么几个，就不一一叙述了，然后清空classic和modern目录下的文件。
5.编译打包
首先执行sencha app build development命令重新生成编译环境，然后执行sencha app build -c命令即可
6.运行
不管是在开发环境还是生产环境我们都可以通过?theme=皮肤名称参数来切换皮肤了
结语：这只是一个基本运用，具体扩展就需要你自己去发掘了。
