运行以下 lint 命令时收到弃用警告

eslint src/js/**/*.js src/js/**/*.jsx webpack.config.js --quiet

警告：

DeprecationWarning: [eslint] 'ecmaFeatures' 配置文件属性已被弃用，并且没有效果。（在 /Users/me/Documents/my-project/node_modules/eslint-config-airbnb/rules/react.js 中找到

这似乎是在抱怨eslint-config-airbnb在react-a11y.js和下列出的文件react.js。这些文件确实包含顶级配置

ecmaFeatures: {
  jsx: true
}

这似乎是不正确的：github issue，docs。但是，似乎（docs）node_modules应该被 eslint 忽略，无论如何，为了明确起见，我已将以下内容添加到我的.eslintignore

node_modules/**/*.*
node_modules

为什么我会收到关于 node_modules 中问题的警告？我唯一能想到的是忽略列表不包括 eslint 本身的配置，但这似乎很牵强，它可能会警告我 node_modules 中每个 eslintrc 文件的每个过期或错误配置？

如果它是相关的，我的.eslintrc.json

{
  "env": {
    "es6": true,
    "browser": true,
    "node": true,
    "jest": true
  },
  "extends": ["airbnb", "prettier", "prettier/react"],
  "parserOptions": {
    "ecmaVersion": 2016,
    "sourceType": "module",
    "ecmaFeatures": {
      "experimentalObjectRestSpread": true,
      "jsx": true
    }
  },
  "plugins": ["prettier", "react"],
  "parser": "babel-eslint",
  "rules": {
    "no-param-reassign": 0
  }
}

我该如何解决这个问题？

编辑：

升级到eslint-config-airbnb@latest（看起来顶级ecmaFeatures问题已经解决）会导致看起来更严重的错误：

/Users/me/Documents/my-project/node_modules/eslint-config-airbnb/rules/react.js:

更新 babel-preset-react 和 eslint-plugin-react，为我解决了这个问题。如果这引发了新的错误，您将被迫更新与 eslint 相关的几乎所有内容。
