How to configure vue-cli to support more than IE9 (ES6 to ES5)

in the vue-cli development environment, the failure to convert ES6 to ES5, at all caused the IE browser to fail to recognize the white screen

try to use various babel plug-ins, but the configuration has no practical effect and is still invalid in the development environment (webpack-dev-server version has also been reduced to 2.5.1)

webpack.base.conf.js 

test: /\.js$/,
loader: "babel-loader",
include: [resolve("src"), resolve("test")],
exclude: /node_modules/

.babelrc 

{
"presets": [
  ["env", {
    "modules": false,
    "targets": {
      "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
  }
 }],
"stage-2"
  ],
 "plugins": ["transform-vue-jsx", "transform-runtime"]
}

expect to run above IE10

Element-ui vue-cli

use babel-polyfill , it will emulate a complete ES2015+ environment

< H2 > has been resolved. The solution is as follows < / H2 >

1, change the devtool parameter, in index.js 

devtool: 'source-map',

so that we can get specific error messages.

2, if we also use API, in ES6, such as Promise, it will not be supported by IE browsers, so we need to refer to 'babel-polyfill' 

webpack.base.conf.js
entry: {
    normal: ['babel-polyfill', './src/main.js']
},
main.js
import 'babel-polyfill';

3, refer to whether the plug-ins have been compiled correctly, and the plug-ins I use, such as element-ui,vis, have not been compiled correctly. Change the 'webpack.base.conf.js' file 

{
    test: /\.js$/,
    loader: 'babel-loader',
    include: [resolve('src'), resolve('test'), resolve('/node_modules/element-ui/src')]
}
// 
{
    test: /node_modules[\\\/]vis[\\\/].*\.js$/,
    loader: 'babel-loader',
    query: {
      cacheDirectory: true,
      presets: [ "babel-preset-es2015" ].map(require.resolve),
      plugins: [
        "transform-es3-property-literals", // -sharp2452
        "transform-es3-member-expression-literals", // -sharp2566
        "transform-runtime" // -sharp2566
      ]
    }
  }
