1. Close eslint

This is just the way to close the Vue cli scaffold. In fact, it is very simple to build/webpack.base.conf.js
Just comment out the eslint rules in the configuration file.

module: {
    rules: [
      // {
      //   test: /\.(js|vue)$/,
      //   loader: 'eslint-loader',
      //   enforce: 'pre',
      //   include: [resolve('src'), resolve('test')],
      //   options: {
      //     formatter: require('eslint-friendly-formatter')
      //   }
      // },

      ...
     ]
     ...
   }

2. Modify the syntax detection of eslint. The file is the. eslintrc.js file in the root directory (the rules are written in rules)

Format:

rules: {
    "Rule name": [Regular value, Rule configuration]
}

Regular values:

"off" or 0 / / close rule
 "warn" or 1 / / as a warning in open rules (does not affect exit code)
"Error" or 2 / / treat the rule as an error (1 when the exit code is triggered)

module.exports = {
  root: true,
  parser: 'babel-eslint',
  parserOptions: {
    //Set "script" (default) or "module" if your code is a module in ECMAScript.
    sourceType: 'module'
  },
  env: {
    browser: true,
  },
  // https://github.com/feross/standard/blob/master/RULES.md#javascript-standard-style
  extends: 'standard',
  // required to lint *.vue files
  plugins: [
    'html'
  ],
  // add your custom rules here
  'rules': {
    // allow paren-less arrow functions
    'arrow-parens': 0,
    // allow async-await
    'generator-star-spacing': 0,
    // allow debugger during development
    'no-debugger': process.env.NODE_ENV === 'production' ? 2 : 0,
    "no-unused-vars": [2, { 
      // Allow declaration of unused variables
      "vars": "local",
      // Parameter not checked
      "args": "none" 
    }],
    // Closing statement force semicolon end
    "semi": [0],
    //No more than 100 empty lines
    "no-multiple-empty-lines": [0, {"max": 100}],
    //Turn off disable mixing tab s and spaces
    "no-mixed-spaces-and-tabs": [0],
  }
}
