Vue2+Webpack+ES6 兼容低版本浏览器(IE)

Vue2+Webpack+ES6 兼容低版本浏览器(IE)

1.解决方式:安装 “babel-polyfill”

1.1命令: npm install --save-dev babel-polyfill

1.2在入口main.js文件引入:import ‘babel-polyfill’

1.3在build文件夹下找到webpack.base.conf.js.修改入口方式:

    entry: {

           app: ["babel-polyfill", "./src/main.js"]

       }

2.依赖一个插件解决ES6/ES7高级语法兼容

2.1 npm install --save-dev babel-preset-es2015-ie

2.2 如果根目录下缺少文件.babelrc,新建一个,如下:

{

  "presets": [

    ["env", {

      "modules": false,

      "targets": {

        "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]

      }

    }],

    "stage-2"

  ],

  "plugins": ["transform-runtime"],

  "env": {

    "test": {

      "presets": ["env", "stage-2"],

      "plugins": ["istanbul"]

    }

  }

}
