我是 eslint 的新手，而且更漂亮。我有这个简单的例子，当我在 .prettierrc.json 文件中使用 "tabWidth": 4 时。我看到了错误。我为了避免它们之间发生冲突，我安装了 eslint-config-prettier。但我仍然得到错误。

文件：

1. 应用.js

import React, { useState } from "react";
function App() {
const [isLoggedIn, setIsLoggedIn] = useState(false);

const lea = 15;

const loginHandler = (email, password) => {
    setIsLoggedIn(true);
};

const logoutHandler = () => {
    setIsLoggedIn(false);
};

return (
    <>
        <MainHeader isAuthenticated={isLoggedIn} onLogout={logoutHandler} />
        <main>
            {!isLoggedIn && <Login onLogin={loginHandler} />}
            {isLoggedIn && <Home onLogout={logoutHandler} />}
        </main>
    </>
);}

导出默认应用程序；

2. .eslintrc.json

{
"env": {
    "browser": true,
    "es2021": true
},
"extends": [
    "plugin:react/recommended",
    "airbnb",
    "plugin:prettier/recommended",
    "eslint:recommended",
    "prettier"
],
"parserOptions": {
    "ecmaFeatures": {
        "jsx": true
    },
    "ecmaVersion": 12,
    "sourceType": "module"
},
"parser": "babel-eslint",
"plugins": ["react", "prettier"],
"rules": {
    "prettier/prettier": ["error"]
}}

3. .prettierrc.json

{
"arrowParens": "always",
"bracketSpacing": true,
"htmlWhitespaceSensitivity": "css",
"insertPragma": false,
"jsxBracketSameLine": false,
"jsxSingleQuote": false,
"printWidth": 86,

"requirePragma": false,
"semi": true,
"singleQuote": false,
"tabWidth": 4,
"trailingComma": "es5",
