Question

所以我最近问了一个关于here的问题，经过大量的搜索和尝试之后，这就是我的babel.rc所拥有的：

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

这就是我的webpack的内容：

let mix = require('laravel-mix');
var path = require('path');

/*

 |--------------------------------------------------------------------------

 | Mix provides a clean, fluent API for defining some Webpack build steps

var npm = '/node_modules/';

var paths = {
  'jquery-ui': npm + 'jquery-ui/',
  'bootstrap': npm + 'bootstrap/',
  'select2': npm + 'select2/dist/',
  'lightbox2': npm + 'lightbox2/dist/',
  'accounting': npm + 'accounting/',
  'polly-fill': npm + '@babel/polyfill/dist/',
};

var jQueryUITheme = 'ui-lightness';

mix.less('resources/assets/less/style.less', 'public/css/', {
  modifyVars: {
    'bootstrap': '"' + path.resolve(__dirname) + paths['bootstrap'] + 'less/' + '"'
  }
}).js('resources/assets/js/boot.js', 'public/js/all.js').webpackConfig({

  ], 'public/js/genesis.js')
  .copy(path.resolve(__dirname) + paths['jquery-ui'] + 'themes/' + jQueryUITheme + '/jquery-ui.min.css', 'public/css/lib/jquery-ui/jquery-ui.min.css')

  .copy(path.resolve(__dirname) + '/resources/assets/js/lib/pace.js', 'public/js/')
  .sourceMaps();

 mix.babel(['public/js/main.js'], 'public/js/main.js');
 mix.babel(['public/js/vue.js'], 'public/js/vue.js');
 mix.minify(['public/js/main.js', 'public/js/vue.js', 'public/css/style.css']);

我理解11即不支持es5以上的任何内容，但是我的vue JS仍未编译到ES5，最后一个问题的输出仍然相同。我对如何将Vue JS编译到ES5感到困惑，以至于我没有得到以下内容：

错误：

SCRIPT1002: Syntax error
vue.js (16,8498)

好吧，这行呢？

(module,__webpack_exports__,__webpack_require__){"use strict";eval("/* unused harmony export getJSON */\n/* unused harmony export getScrollBarWidth */\n/* unused harmony export translations */\n/* harmony export (immutable) */ __webpack_exports__[\"b\"] = delayer;\n/* unused harmony export VueFixer */\n// coerce convert som types of data into another type\nconst coerce = {\n  // Convert a string to booleam. Otherwise, return the value without modification, so if is not boolean, Vue throw a warning.\n  boolean: val => (typeof val === 'string' ? val === '' || val === 'true' ? true : (val === 'false' || val === 'null' || val === 'undefined' ? false : val) : val),\n  // Attempt to convert a string value to a Number. Otherwise, return 0.\n  number: (val, alt = null) => (typeof val === 'number' ? val : val === undefined || val === null || isNaN(Number(val)) ? alt :

我不确定我正在使用哪个版本的Webpack，因为我正在使用Laravel Mix，但是我正在使用babel 6。

一切正常，但是Vue JS仍然无法正确编译到IE 11的ES5。

Answer 1

捆绑代码中的

number: (val, alt = null) => (typeof val === 'number' ? val : val === undefined.....对我说，箭头功能未转换为普通功能。尝试添加transform-es2015-arrow-functions babel插件。如果您仍然会遇到类似的错误，请尝试分析捆绑软件的代码并找出其中的ES6 feature not supported by IE11。

无法为IE 11编译Vue.js
