reactjs - 在定义之前使用了“React”

Question

我正在使用 create-react-app + typescript + eslint 应用程序，并且在构建过程中出现这样的错误：

Line 1:8:  'React' was used before it was defined  @typescript-eslint/no-use-before-define

我的组件中的代码以：

import React from "react";

埃斯林特设置：

module.exports = {
  parser: "@typescript-eslint/parser",
  parserOptions: {
    ecmaVersion: 2020,
    sourceType: "module",
    ecmaFeatures: {
      jsx: true
    }
  },
  settings: {
    react: {
      version: "detect"
    }
  },
  extends: [
    "plugin:react/recommended",
    "plugin:@typescript-eslint/recommended",
    "prettier/@typescript-eslint",
    "plugin:prettier/recommended"
  ],
  rules: {
    "@typescript-eslint/explicit-module-boundary-types": 0,
    "@typescript-eslint/triple-slash-reference": 0,
    "no-use-before-define": "off",
    "@typescript-eslint/no-use-before-define": "off"
  },
};

package.json 的某些部分：

"devDependencies": {
  "@typescript-eslint/eslint-plugin": "^4.1.0",
  "@typescript-eslint/parser": "^4.1.0",
  "babel-eslint": "^10.1.0",
  "eslint": "^6.6.0",
  "eslint-config-airbnb": "^18.1.0",
  "eslint-config-prettier": "^6.11.0",
  "eslint-plugin-import": "^2.20.2",
  "eslint-plugin-prettier": "^3.1.3",
  "eslint-plugin-react": "^7.20.0",
  "prettier": "^2.0.5",
  "start-server-and-test": "^1.11.3"
},
"dependencies": {
  ...
  "react-scripts": "3.4.3",
  ...
}

我试过了：

• 阅读https://github.com/typescript-eslint/typescript-eslint/issues/2502
• 在 .eslintrc.js 中禁用 @typescript-eslint/no-use-before-define 和 no-use-before-define
• 实际上我试图完全删除 .eslintrc.js ，但有同样的错误。

来自官方文档。

"rules": {
  // note you must disable the base rule as it can report incorrect errors
  "no-use-before-define": "off",
  "@typescript-eslint/no-use-before-define": ["error"]
}
