vscode ESLint格式不正确老是报错 more than 1 blank line not allowed

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 filesplugins: ['html','vue'],// add your custom rules here//it is base on https://github.com/vuejs/eslint-config-vue'rules': {'accessor-pairs': 2,'arrow-spacing': [2, {'before': true,'after': true}],'block-spacing': [2, 'always'],'brace-style': [2, '1tbs', {'allowSingleLine': true}],'camelcase': [0, {'properties': 'always'}],'comma-dangle': [2, 'never'],'comma-spacing': [2, {'before': false,'after': true}],'comma-style': [2, 'last'],'constructor-super': 2,'curly': [2, 'multi-line'],'dot-location': [2, 'property'],'eol-last': 2,'eqeqeq': [2, 'allow-null'],'generator-star-spacing': [2, {'before': true,'after': true}],'handle-callback-err': [2, '^(err|error)$'],'indent': [2, 2, {'SwitchCase': 1}],'jsx-quotes': [2, 'prefer-single'],'key-spacing': [2, {'beforeColon': false,'afterColon': true}],'keyword-spacing': [2, {'before': true,'after': true}],'new-cap': [2, {'newIsCap': true,'capIsNew': false}],'new-parens': 2,'no-array-constructor': 2,'no-caller': 2,'no-console': 'off','no-class-assign': 2,'no-cond-assign': 2,'no-const-assign': 2,'no-control-regex': 0,'no-delete-var': 2,'no-dupe-args': 2,'no-dupe-class-members': 2,'no-dupe-keys': 2,'no-duplicate-case': 2,'no-empty-character-class': 2,'no-empty-pattern': 2,'no-eval': 2,'no-ex-assign': 2,'no-extend-native': 2,'no-extra-bind': 2,'no-extra-boolean-cast': 2,'no-extra-parens': [2, 'functions'],'no-fallthrough': 2,'no-floating-decimal': 2,'no-func-assign': 2,'no-implied-eval': 2,'no-inner-declarations': [2, 'functions'],'no-invalid-regexp': 2,'no-irregular-whitespace': 2,'no-iterator': 2,'no-label-var': 2,'no-labels': [2, {'allowLoop': false,'allowSwitch': false}],'no-lone-blocks': 2,'no-mixed-spaces-and-tabs': 2,'no-multi-spaces': 2,'no-multi-str': 2,'no-multiple-empty-lines': [2, {'max': 1}],'no-native-reassign': 2,'no-negated-in-lhs': 2,'no-new-object': 2,'no-new-require': 2,'no-new-symbol': 2,'no-new-wrappers': 2,'no-obj-calls': 2,'no-octal': 2,'no-octal-escape': 2,'no-path-concat': 2,'no-proto': 2,'no-redeclare': 2,'no-regex-spaces': 2,'no-return-assign': [2, 'except-parens'],'no-self-assign': 2,'no-self-compare': 2,'no-sequences': 2,'no-shadow-restricted-names': 2,'no-spaced-func': 2,'no-sparse-arrays': 2,'no-this-before-super': 2,'no-throw-literal': 2,'no-trailing-spaces': 2,'no-undef': 2,'no-undef-init': 2,'no-unexpected-multiline': 2,'no-unmodified-loop-condition': 2,'no-unneeded-ternary': [2, {'defaultAssignment': false}],'no-unreachable': 2,'no-unsafe-finally': 2,'no-unused-vars': [2, {'vars': 'all','args': 'none'}],'no-useless-call': 2,'no-useless-computed-key': 2,'no-useless-constructor': 2,'no-useless-escape': 0,'no-whitespace-before-property': 2,'no-with': 2,'one-var': [2, {'initialized': 'never'}],'operator-linebreak': [2, 'after', {'overrides': {'?': 'before',':': 'before'}}],'padded-blocks': [2, 'never'],'quotes': [2, 'single', {'avoidEscape': true,'allowTemplateLiterals': true}],'semi': [2, 'never'],'semi-spacing': [2, {'before': false,'after': true}],'space-before-blocks': [2, 'always'],'space-before-function-paren': [2, 'never'],'space-in-parens': [2, 'never'],'space-infix-ops': 2,'space-unary-ops': [2, {'words': true,'nonwords': false}],'spaced-comment': [2, 'always', {'markers': ['global', 'globals', 'eslint', 'eslint-disable', '*package', '!', ',']}],'template-curly-spacing': [2, 'never'],'use-isnan': 2,'valid-typeof': 2,'wrap-iife': [2, 'any'],'yield-star-spacing': [2, 'both'],'yoda': [2, 'never'],'prefer-const': 2,'no-debugger': process.env.NODE_ENV === 'production' ? 2 : 0,'object-curly-spacing': [2, 'always', {objectsInObjects: false}],'array-bracket-spacing': [2, 'never']}
}

5、设置vscode配置文件自动纠错

window电脑：文件 > 首选项 > 设置点击右上角的{}

出现setting.json文件

{"[typescript]": {"editor.formatOnSave": true,"editor.formatOnPaste": true},"[markdown]": {"editor.formatOnSave": true,"editor.wordWrap": "on","editor.renderWhitespace": "all","editor.acceptSuggestionOnEnter": "off"},"editor.fontSize": 18}
