我的 react 代码正常:

import React from 'react';
import Header from '../components/Common/Header';

// ...
header: (props) => <Header {...props} />
// ...other code

我只是想证明所有的 imports 都被使用了，但仍然给出错误的错误。

我正在使用 ESlint 配置 no-unused-vars 规则，但不幸的是它正在这样做:

E:\React\sg_app\src\containers\Todo\TodoScreen.js
  1:8   error  'React' is defined but never used                 no-unused-vars
  2:10  error  'View' is defined but never used                  no-unused-vars
  2:28  error  'StatusBar' is defined but never used             no-unused-vars
  5:8   error  'TodoFilter' is defined but never used            no-unused-vars
  6:8   error  'TodoListView' is defined but never used  

我的eslint配置

module.exports = {
  "extends": "eslint:recommended",
  "parser": "babel-eslint",
  "env": {
    "es6": true,
    "jest": true,
  },
  "parserOptions": {
    "sourceType": "module",
  },
  "rules": {
      "semi": "warn",
      "no-unused-vars": "warn",
      "no-use-before-define": "off",
      "no-multiple-empty-lines": ["warn", {"max": 2}],
      "no-console": "warn",
      "arrow-parens": ["error", "as-needed"],
      "comma-dangle": "off",
      // "import/first": "error"
  }
};

我如何阻止 eslint 向 React、View 等用作组件但错误地显示为未使用的导入提供错误？

最佳答案

回答这个以供任何人将来引用 我根据@FunkeyFlo 的建议找到了解决方法 谢谢你的建议 plugin:react/recommended 这个npmjs.com/package/eslint-plugin-react为了使 eslint 在 react 中工作，package extend 是必需的。

"extends": [
    "eslint:recommended",
    "plugin:react/recommended"  //this plugin is required to use eslint for react, otherwise we will get errors for 'React' import, as 'no-unused-vars'
  ],
