业务需求：B项目要用到A项目部分代码

调试问题：当调试B项目时报错，如图

注意绿色部分的代码，是A中的代码才有tabBar

B项目的json文件如下：

{
  "pages": [
    "pages/tabBar/shop/index",
    "pages/tabBar/case/index",
    "pages/people/case/detail"
  ],
  "window": {
    "navigationBarTextStyle": "black",
    "navigationBarTitleText": "松鼠大脑",
    "navigationBarBackgroundColor": "#f8f8f8",
    "backgroundColor": "#f8f8f8"
  },
  "tabBar": {
    "color": "#888888",
    "selectedColor": "#3cc51f",
    "iconColor": "#3cc51f",
    "borderStyle": "white",
    "backgroundColor": "#f0eff5",
    "list": [
      {
        "pagePath": "pages/tabBar/shop/index",
        "iconPath": "assets/images/shopH.png",
        "selectedIconPath": "assets/images/shopHL.png",
        "text": "官网"
      },
      {
        "pagePath": "pages/tabBar/case/index",
        "iconPath": "assets/images/jobH.png",
        "selectedIconPath": "assets/images/jobHL.png",
        "text": "案例"
      }
    ]
  },
  "subPackages": [
    {
      "root": "pages/shop/",
      "pages": [
        "detail"
      ]
    }
  ],
  "networkTimeout": {
    "request": 10000,
    "connectSocket": 10000,
    "uploadFile": 10000,
    "downloadFile": 10000
  },
  "debug": true
}

备注：APPID都不不一样的，开发者为同一人
