Eslint错误导致create-react-app编译失败

编程问答 2022-06-04

问题描述

我正在使用create-react-app建立一个网站，并且刚刚为其安装了eslint。

由于某种原因，本应显示为拖欠警告的内容显示为错误，并导致npm run start失败。

如何绕过此问题，并像以前一样将其显示为警告？

我的.eslintrc.js 

  env: {
    browser: true,es6: true,jest: true,},extends: [
    'airbnb-typescript','plugin:@typescript-eslint/recommended','prettier/react','prettier/@typescript-eslint','plugin:prettier/recommended',],globals: {
    Atomics: 'readonly',SharedArrayBuffer: 'readonly',parser: '@typescript-eslint/parser',parserOptions: {
    ecmaFeatures: {
      jsx: true,ecmaVersion: 2018,sourceType: 'module',project: './tsconfig.json',plugins: ['react','@typescript-eslint'],rules: {
    'class-methods-use-this': 'off','additional-rule': 'warn',ignorePatterns: ['**/node_modules/*','**/build/*','config-overrides.js'],};

我的package.json 

  "name": "device-protection-renewal-web","version": "0.1.0","private": true,"dependencies": {
    "@testing-library/jest-dom": "^5.11.5","@testing-library/react": "^11.1.0","@testing-library/user-event": "^12.1.10","@types/jest": "^26.0.15","@types/node": "^12.19.3","@types/react": "^16.9.55","@types/react-dom": "^16.9.9","babel-polyfill": "^6.26.0","core-js": "^3.6.5","i18next": "^19.8.3","react": "^17.0.1","react-app-polyfill": "^2.0.0","react-dom": "^17.0.1","react-i18next": "^11.7.3","react-scripts": "4.0.0","web-vitals": "^0.2.4"

解决方法

对不起。我不允许发表评论，但我真的想为您提供帮助。

我假设您已经使用npm install eslint --save-dev安装了eslint，并使用node_modules/.bin/eslint --init回答了提示中的问题定义了默认配置。

我注意到在您的.eslintrc.js文件中，扩展选项中缺少eslint设置：

extends: [
    'eslint:recommended','airbnb-typescript','plugin:@typescript-eslint/recommended','prettier/react','prettier/@typescript-eslint','plugin:prettier/recommended',],

还建议eslint在package.json中使用您自己的脚本，并使用npm run lint运行该脚本，并在您最喜欢的代码编辑器中将其与eslint插件结合使用：

{
  "scripts": {
    "start": "react-scripts start",// ...
    "lint": "eslint ."
  },}

可能稍后会构建您的应用程序，因此您应该创建一个.eslintignore文件，并在其中添加build，因为在运行命令时会检查build目录中的文件。>
