//这个是从镜像源下载
cnpm install -g @vue/cli 

vue --version

//vuetest是我的项目名
vue create vue-element-plus

>( ) Babel                              //  代码编译
 ( ) TypeScript                         //  ts
 ( ) Progressive Web App (PWA) Support  //  支持渐进式网页应用程序
 ( ) Router                             //  vue路由
 ( ) Vuex                               //  状态管理模式
 ( ) CSS Pre-processors                 //  css预处理
 ( ) Linter / Formatter                 //  代码风格、格式校验
 ( ) Unit Testing                       //  单元测试
 ( ) E2E Testing                        //  端对端测试

**hash：**
特征：
1.hash会在浏览器路径里带#号，比如http://locahost:8080/#/index
2.hash在浏览器改变路径触发页面跳转，即前进后退，但不会重新加载页面。
3.hash传参是基于url，如果要传递复杂的参数会有体积的限制


**history**
特征：
1.可以在url放参数，而且也可以将数据存放在一个特定的对象中，其利用HTML5 History inteface中新增的pushState()和replaceState()方法（限制：history只支持IE8以上）

2.需要后台配置支持,前端的 URL 必须和实际向后端发起请求的 URL 一致，如 http://www.test.com/user/id 如果后端缺少对 /user/id 的路由处理，将返回 404 错误。
