本文主要是介绍elsint报错Delete `␍`eslintprettier/prettier，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一，原因
这篇博客写得很清楚：解决VSCode Delete `␍`eslint(prettier/prettier)错误_vscode 删除cr-CSDN博客
还有这篇文章，解决办法很详细：滑动验证页面
二，解决办法
根目录下新建.prettierrc.js文件
module.exports = {trailingComma: "all", // 设置是否末尾添加逗号的字段arrowParens: "avoid", //箭头函数参数括号,avoid 能省略括号的时候就省略useEditorConfig: false,endOfLine: "auto", //避免报错delete (cr)的错bracketSameLine: true,jsxSingleQuote: true,singleQuote: false, // 格式化以单引号为主semi: true, // 格式化不加分号printWidth: 300,
};
根目录下.eslintrc.js文件（可以不配置）
module.exports = {env: {browser: true,es6: true,node: true,},extends: ["plugin:vue/essential","airbnb-base","plugin:prettier/recommended", //这样写，让pettier的规则，放在eslint规则扩展中，于是会经由eslint报错],globals: {Atomics: "readonly",SharedArrayBuffer: "readonly",},parserOptions: {ecmaVersion: 2018,sourceType: "module",},plugins: ["vue"],rules: {quotes: [2, "double"], //警告，必须双引号"no-compare-neg-zero": 2, //禁止与 -0 进行比较"no-cond-assign": [2, "except-parens"], //禁止条件语句中出现赋值操作符"no-console": 0, //允许出现console"no-constant-condition": 2, //禁止在条件中使用常量表达式"no-control-regex": 2, //禁止在正则表达式中使用控制字符"no-debugger": 0, //可以使用debugger"no-dupe-args": 2, //禁止 function 定义中出现重名参数"no-dupe-keys": 2, //禁止对象字面量中出现重复的 key"no-duplicate-case": 2, //禁止出现重复的 case 标签"no-empty": 2, //禁止出现空语句块"no-empty-character-class": 2, //禁止在正则表达式中使用空字符集"no-ex-assign": 2, //禁止对 catch 子句的参数重新赋值"no-extra-boolean-cast": 2, //禁止不必要的布尔转换"no-extra-parens": ["error", "functions"], //禁止不必要的括号"no-extra-semi": 2, //禁止不必要的分号"no-func-assign": 2, //禁止对 function 声明重新赋值"no-inner-declarations": 0, //禁止在嵌套的块中出现变量声明或 function 声明"no-invalid-regexp": 2, //禁止 RegExp 构造函数中存在无效的正则表达式字符串"no-irregular-whitespace": 2, //禁止不规则的空白"no-obj-calls": 2, //禁止把全局对象作为函数调用"no-prototype-builtins": 2, //禁止直接调用 Object.prototypes 的内置属性"no-regex-spaces": 2, //禁止正则表达式字面量中出现多个空格"no-sparse-arrays": 2, //禁用稀疏数组"no-template-curly-in-string": 0, //禁止在常规字符串中出现模板字面量占位符语法"no-unexpected-multiline": 2, //禁止出现令人困惑的多行表达式"no-unreachable": 2, //禁止在 return、throw、continue 和 break 语句之后出现不可达代码"no-unsafe-finally": 2, //禁止在 finally 语句块中出现控制流语句"no-unsafe-negation": 2, //禁止对关系运算符的左操作数使用否定操作符"use-isnan": 2, //要求使用 isNaN() 检查 NaN"valid-jsdoc": "off", //"valid-typeof": 2, //强制 typeof 表达式与有效的字符串进行比较curly: 2, //强制所有控制语句使用一致的括号风格"consistent-return": [2,{treatUndefinedAsUnspecified: true,},],"default-case": 2,eqeqeq: "off","guard-for-in": 0,"no-case-declarations": 0,"no-empty-pattern": 2,"no-fallthrough": 2,"no-global-assign": [2,{exceptions: [],},],"no-octal": 2,"no-redeclare": 2,"no-self-assign": 2,"no-unused-labels": 2,"no-useless-escape": 2,strict: 2,"no-delete-var": 2,"no-undefined": 0,"no-undef": 2,"no-use-before-define": 2,"array-bracket-spacing": [2, "never"],"block-spacing": [2, "always"],"brace-style": [2, "1tbs"],"comma-dangle": ["error", "never"],"comma-spacing": [2,{before: false,after: true,},],"comma-style": [2, "last"],"computed-property-spacing": ["error", "never"],"eol-last": [2, "always"],"func-call-spacing": ["error", "never"],indent: ["error",2,{SwitchCase: 1,},],"jsx-quotes": ["error", "prefer-double"],"key-spacing": ["error",{beforeColon: false,afterColon: true,},],"new-cap": ["error",{newIsCap: true,capIsNewExceptionPattern: "(Type[a-zA-Z0-9]+|Deco[a-zA-Z0-9]+)+",},],"new-parens": "error","no-mixed-spaces-and-tabs": 2,"no-multi-assign": "error","no-multiple-empty-lines": "error",semi: [2,"always",{omitLastInOneLineBlock: true,},],"constructor-super": 2,"no-class-assign": 0,"no-const-assign": 2,"no-this-before-super": 2,"no-var": 2,"no-dupe-class-members": 2,"no-new-symbol": 2,"require-yield": 2,"prefer-const": 0,},
