修改 vue2.0在 ios8上出现白屏状态

自己搭建的vue框架遇到的问题原因是es6转es5的问题
1.npm install babel-polyfill es6-promise babel-preset-env --save-dev
2.在package.json里写上

"babel": {    "presets": [      "env"    ],    "plugins": []  },

3.webpack.config.js

entry = {     app: ["babel-polyfill", "./src/main.js"]     
},{           
 test: /\.js$/,         
 exclude: /(node_modules)/,         
 use: [          
  {            
   loader: 'babel-loader',            
    options: {               
    presets: ['es2015', 'stage-0'],             
 }           
}       

 ]       
},
