mpvue小程序tabBar怎么设置呢，有具体描述，请教下哈

Question

贴出mpvue-quickstart项目创建初始代码：
src/app.json:

{
    "pages": [
        "pages/index/main",
        "pages/logs/main",
        "pages/counter/main"
    ],
    "window": {
        "backgroundTextStyle": "light",
        "navigationBarBackgroundColor": "#fff",
        "navigationBarTitleText": "WeChat",
        "navigationBarTextStyle": "black"
    }
}

src/main.js

import Vue from 'vue'
import App from './App'

import  '../static/weui/weui.css'

Vue.config.productionTip = false
App.mpType = 'app'

const app = new Vue(App)
app.$mount()

请问怎么设置tabBar呢？

"tabBar": {
      "color": "#999",
      "selectedColor": "#1aad16",
      "backgroundColor": "#fff",
      "borderStyle": "#fff",
      "list": [{
        "pagePath": "pages/counter/main",
        "text": "发现1"
      }, {
        "pagePath": "pages/index/main",
        "text": "主页"
      }]
    }

Answer 1

src/main.js

export default {
  // 这个字段设置路由、title、tabbar
  config: {
    // 页面前带有 ^ 符号的，会被编译成首页，其他页面可以选填，我们会自动把 webpack entry 里面的入口页面加进去
    // eslint检测字符串必须用单引号
    "pages": [
      "^pages/index/main",
      "pages/tabbar/main"
    ],
    "window": {
      "backgroundTextStyle": "light",
      "navigationBarBackgroundColor": "#fff",
      "navigationBarTitleText": "WeChat",
      "navigationBarTextStyle": "black"
    },
    "tabBar": {
      "color": "#999",
      "selectedColor": "#1aad16",
      "backgroundColor": "#fff",
      "borderStyle": "#fff",
      "list": [{
        "pagePath": "pages/index/main",
        "text": "发现1"
      }, {
        "pagePath": "pages/tabbar/main",
        "text": "主页"
      }]
    }
  }
}

src/app.json

{
    "pages": [
        "pages/index/main",
        "pages/logs/main",
        "pages/counter/main",
        "pages/tabbar/main"
    ],
    "window": {
        "backgroundTextStyle": "light",
        "navigationBarBackgroundColor": "#fff",
        "navigationBarTitleText": "WeChat",
        "navigationBarTextStyle": "black"
    },
    "tabBar": {
      "color": "#999",
      "selectedColor": "#1aad16",
      "backgroundColor": "#fff",
      "borderStyle": "#fff",
      "list": [{
        "pagePath": "pages/index/main",
        "text": "发现1"
      }, {
        "pagePath": "pages/tabbar/main",
        "text": "主页"
      }]
    }
}

真是不懂，后面我把main.js中export default {}屏蔽了，tabBar也正常了。。。。
