代码如下：

{

 “pages”: [

    “pages/index/index”

  ],

  “window”: {

    “backgroundTextStyle”: “light”,

    “navigationBarBackgroundColor”: “#fff”,

    “navigationBarTitleText”: “WeChat”,

    “navigationBarTextStyle”: “black”

  },

}

出错如下：undefined
Expecting ‘STRING’, got }
   8 |     “navigationBarTitleText”: “WeChat”,
   9 |     “navigationBarTextStyle”: “black”
> 10 |   },
     |   ^
  11 | }
  12 |请问这个哪里有问题呀？
