### ***报错背景*** ###

ESLint格式太严谨，老是报错 ！

***解决方案：***

让ESLint自动纠正格式

1、安装ESLint

2、安装vetur

3、package.json里面有eslint配置参数

4、.eslintrc.js文件配置如下

module.exports = {
      root: true,
      parser: 'babel-eslint',
      parserOptions: {
      sourceType: 'module',
      "allowImportExportEverywhere": true  //ignore eslint error: 'import' and 'export' may only appear at the top level
      },
      env: {
        browser: true,
        node: true,
        es6: true,
      },
      extends: 'eslint:recommended',
      // required to lint *.vue files
      plugins: [
        'html',
        'vue'
      ],
      // add your custom rules here
      //it is base on https://github.com/vuejs/eslint-config-vue
