解决白屏（vue）

1.npm安装

npm install babel-polyfill
npm install es6-promise

 package.json中会出现

"babel-polyfill": "^6.26.0",
"es6-promise": "^4.1.1",

  

2.main.js引入

import 'babel-polyfill'
import Vue from 'vue'
import Es6Promise from 'es6-promise'
require('es6-promise').polyfill()
Es6Promise.polyfill()

3.webpack.base.conf.js

module.exports = {

entry: {
    app: ['babel-polyfill', './src/main.js']
},

module: {
    rules: [{
            test: /.vue$/,
            loader: 'vue-loader',
            options: vueLoaderConfig
        },
        {
            test: /.js$/,
            loader: 'babel-loader',
            query:{presets:['es2015']},
            include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
        },

4.在.babelrc文件里加入

{
"presets":["es2015", "stage-2"],
}
