javascript - 无法为 IE 11 编译 Vue.js

Question

所以我最近问了一个关于这个的问题 here经过大量谷歌搜索和尝试之后，这就是我的 babel.rc 内容:

{
  "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:

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

/*
 |--------------------------------------------------------------------------
 | Mix Asset Management
 |--------------------------------------------------------------------------
 |
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel application. By default, we are compiling the Sass
 | file for the application as well as bundling up all the JS files.

 */

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({
  resolve: {
    alias: {
      "matches-selector/matches-selector": "desandro-matches-selector",
      "eventEmitter/EventEmitter": "wolfy87-eventemitter",
      "get-style-property/get-style-property": "desandro-get-style-property",
      'masonry': 'masonry-layout',
      'isotope': 'isotope-layout',
      'isotope/js/layout-mode': 'isotope-layout/js/layoutmode',
      'pace': 'pace-progress',
      "jquery-ui/ui/widget": "jquery-ui/widget.js",
    }
  },
}).js('resources/assets/js/vue/main.js', 'public/js/vue.js')
  .scripts([
    'resources/assets/js/lib/jquery.validate.min.js',
    'resources/assets/js/lib/jquery.bootstrap.wizard.min.js',
    path.resolve(__dirname) + paths['accounting'] + 'accounting.js'
  ], '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) + paths['jquery-ui'] + 'themes/' + jQueryUITheme + '/theme.css', 'public/css/lib/jquery-ui/theme.css')
  .copy(path.resolve(__dirname) + paths['jquery-ui'] + 'themes/' + jQueryUITheme + '/images', 'public/css/lib/jquery-ui/images')
  .copy(path.resolve(__dirname) + paths['select2'] + 'css/select2.min.css', 'public/css/lib/select2/select2.min.css')
  .copy(path.resolve(__dirname) + paths['lightbox2'] + 'css/lightbox.min.css', 'public/css/lib/lightbox2/css')
  .copy(path.resolve(__dirname) + paths['lightbox2'] + 'images/loading.gif', 'public/css/lib/lightbox2/images')
  .copy(path.resolve(__dirname) + paths['lightbox2'] + 'images/close.png', 'public/css/lib/lightbox2/images')
  .copy(path.resolve(__dirname) + paths['lightbox2'] + 'images/next.png', 'public/css/lib/lightbox2/images')
  .copy(path.resolve(__dirname) + paths['lightbox2'] + 'images/prev.png', 'public/css/lib/lightbox2/images')
  .copy(path.resolve(__dirname) + paths['polly-fill'] + 'polyfill.min.js', 'public/js/')
  .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']);

我了解 ie 11 无论如何都不支持 es5 以上的任何内容，但是我的 vue JS 仍未编译为 ES5，我上一个问题的输出仍然相同。我对如何将 Vue JS 编译为 ES5 感到困惑，因此我没有得到以下信息:

错误:

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

好的，那么这一行是什么？

(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 :

我不确定我使用的是哪个版本的 webpack，因为我使用的是 Laravel Mix，但我使用的是 babel 6。

一切都可以正常编译，但 Vue JS 仍然无法正确编译为 IE 11 的 ES5。

Answer 1

number: (val, alt = null) => (typeof val === 'number' ? val : val === undefined..... 在你的捆绑代码中对我说箭头函数没有转换为普通函数。尝试添加 transform-es2015-arrow-functions babel 插件。如果您仍然遇到类似的错误 - 尝试分析您的包的代码并找到哪个 ES6 feature not supported by IE11留在那里。
