reactjs - .eslintrc.js 用于 React 17 和 JSX，无需导入 'react'

Question

在 react 17 中不一定使用

import React from 'react';

但是如果我没有它，那么 eslint 给了我错误

'React' must be in scope when using JSX react/react-in-jsx-scope

知道如何修改 .eslintrc.js

module.exports = {
  parser: "babel-eslint",
  env: {
    browser: true,
    node: true,
    es6: true,
    jest: true,
  },
  extends: [
    "eslint:recommended",
    "plugin:react/recommended",
    "plugin:jsx-a11y/recommended"
    ],
  plugins: [
    "react",
    "react-hooks",
    "jsx-a11y",
  ],
  rules: {
    strict: 0,
    "react-hooks/rules-of-hooks": "error",
    "react-hooks/exhaustive-deps": "warn"
  },
  settings: {
    react: {
      version: "detect"
    }
  }
}

react 17？
非常感谢

您可以在 React docs 中阅读有关它的信息.

If you are using eslint-plugin-react, the react/jsx-uses-react and react/react-in-jsx-scope rules are no longer necessary and can be turned off or removed.

{
  // ...
  "rules": {
    // ...
    "react/jsx-uses-react": "off",
    "react/react-in-jsx-scope": "off"
  }
}

react-in-jsx-scope on github .

要使其工作，您应该将这些规则添加到您的 eslint 中。配置，见 Extending or replacing the default ESLint config对于 Create-React-App 细节，每个框架都应该在他们的文档中有相关部分。
