基于mpvue+vant-weapp+flyio+vuex搭建小程序环境遇到的一些问题及解决方法

mpvue 安装比较简单，直接就把官方的步骤贴过来了

# 全局安装 vue-cli
$ npm install --global vue-cli

# 创建一个基于 mpvue-quickstart 模板的新项目
$ vue init mpvue/mpvue-quickstart my-project

# 安装依赖
$ cd my-project
$ npm install
# 启动构建
$ npm run dev

1.在mpvue + vuex项目中我们不能通过vue那种方式来将store对象实例注入到每个子组件中从而无法使用this.$store.state.xxx、this.$store.dispatch 等来访问或操纵数据仓库中的数据
解决方法：

//在mpvue搭建的项目中的 /src/main.js
import store from './store/index'
Vue.prototype.$store = store;

2.mpvue是不支持路由跳转的，所以我们需要安装个插件mpvue-router-patch,就可以像在vue中一样操作路由跳转了

import MpvueRouterPatch from 'mpvue-router-patch'
Vue.use(MpvueRouterPatch)

3.引入vant-weapp ui框架的时候报错

在这里先说下引入方法，在git上直接下载对应的压缩包，将压缩包中的dist目录解压并放到mpvue项目中的static目录下并重命名dist为vant，然后在app.json增加组件
