vue-cli 如何配置支持IE9以上 (ES6 转 ES5)

Question

在用vue-cli开发环境中遇到根本没有将ES6转成ES5，导致IE浏览器无法识别出现白屏

尝试使用各种babel插件，配置都没有实际作用，在开发环境中还是无效（webpack-dev-server 版本也降低到了2.5.1）

相关代码

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"]
}

期望在IE10以上跑起来

Answer 1

使用babel-polyfill，它会仿效一个完整的 ES2015+ 环境

Answer 2

已解决，解决方案如下

1,更改devtool参数,在index.js中

devtool: 'source-map',

这样我们就能得到具体的错误信息.

2,如果我们还使用了ES6中的API，比如Promise，它将不会得到IE浏览器的支持，所以我们需要引用 'babel-polyfill'

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

3，引用插件是否已经得到正确的编译,我所使用到的插件，比如element-ui,vis等没有得到正确的编译，更改 'webpack.base.conf.js'文件

{
    test: /\.js$/,
    loader: 'babel-loader',
    include: [resolve('src'), resolve('test'), resolve('/node_modules/element-ui/src')]
}

// 前提是你必须安装对应的工具依赖
{
    test: /node_modules[\\\/]vis[\\\/].*\.js$/,
    loader: 'babel-loader',
    query: {
      cacheDirectory: true,
      presets: [ "babel-preset-es2015" ].map(require.resolve),
      plugins: [
        "transform-es3-property-literals", // #2452
        "transform-es3-member-expression-literals", // #2566
        "transform-runtime" // #2566
      ]
    }
  }
