eslint TypeScript 使用随机 .js 文件作为配置并失败

Question

我已将 eslint v9 新安装到我的 TypeScript 项目中。 我的文件根目录中有这个

eslint.config.mjs

。

import eslint from '@eslint/js';
import tseslint from 'typescript-eslint';

export default tseslint.config({
  files: ['**/*.ts'],
  extends: [
    eslint.configs.recommended,
    ...tseslint.configs.strict,
  ]
});

它基本上按预期工作，但我在生成的 javascript 文件中也遇到错误；由 npm 包中的 eslint 指令引起；例如我看到 ChartJs 生成的文件：

/ProjectRoot/wwwroot/dist/js/vendors-node_modules_chart_js_auto_auto_js.js
   3346:5  error    Definition for rule '@typescript-eslint/no-empty-function' was not found       @typescript-eslint/no-empty-function
  12515:9  error    Definition for rule '@typescript-eslint/no-use-before-define' was not found    @typescript-eslint/no-use-before-define
  12545:5  error    Definition for rule '@typescript-eslint/no-use-before-define' was not found    @typescript-eslint/no-use-before-define
  13490:5  warning  Unused eslint-disable directive (no problems were reported from 'complexity')
  13559:5  error    Definition for rule '@typescript-eslint/no-use-before-define' was not found    @typescript-eslint/no-use-before-define
  13562:1  warning  Unused eslint-disable directive (no problems were reported from 'complexity')
  14621:1  warning  Unused eslint-disable directive (no problems were reported from 'complexity')

如果我运行

npx eslint --debug

我会在上面的示例中看到这一点：

eslint:eslint Lint /ProjectRoot/wwwroot/dist/js/vendors-node_modules_chart_js_auto_auto_js.js +0ms
eslint:linter Linting code for /ProjectRoot/wwwroot/dist/js/vendors-node_modules_chart_js_auto_auto_js.js (pass 1) +0ms

所以它似乎使用 javascript 文件作为配置。 对于每个失败的 JavaScript 文件都是如此；它使用该文件作为配置。

### etc...

所以它是从顶部开始执行的，包括配置文件，然后是我的 webpack.config.js 文件，其自身作为配置

这是一个 eslint bug 吗？或者我错过了什么？

调试日志有点误导。这意味着 ESLint 尝试使用平面配置对给定名称的文件进行 lint 检测，请参阅源代码。它确实不意味着 ESLint 尝试将这些文件用作平面配置。

默认情况下，ESLint 包含存储库中的所有 JavaScript 文件，除非明确忽略它们。您正在尝试对构建和缩小的代码进行 lint 处理，预计这些代码会出现 lint 问题。要排除文件或文件夹，请使用

ignores

选项:

import eslint from '@eslint/js';
import tseslint from 'typescript-eslint';

export default tseslint.config({
  files: ['**/*.ts'],
  ignores: [
    'dist/', // exclude specific folder
    '**/*.js', // exclude all JavaScript files
  ],
  extends: [
    eslint.configs.recommended,
    ...tseslint.configs.strict,
  ]
});
