谁能弄清楚我该如何解决 linter 错误。此代码经过测试并且可以完美运行。唯一的问题是我无法将它部署在云功能基础设施上。

我确定 .eslintrc 文件有问题。谁能帮助我了解如何使用传播运算符。

这是 linter 抛出错误的地方:

const rightChoices = _.map(snapshot.val(), (val, questionId) => {
  return { ...val, questionId};
})

这是我的 .eslintrc 文件:

对于后代,因为这有 500 次浏览并且没有解决方案:这对我有用 -

在 .eslintrc.json 更改

"parserOptions": {
   // Required for certain syntax usages
   "ecmaVersion": 2017,
   "sourceType": "module"
 },

"parserOptions": {
   // Required for certain syntax usages
   "ecmaVersion": 2019,
   "sourceType": "module"
 },

然后尝试重新部署

ESLint 确实支持对象休息/传播,但您必须通过配置选择加入。您可以将您的 ecmaVersion 设置为 2018(在 parserOptions 中),或将 ecmaFeatures.experimentalObjectRestSpread 设置为 true(也在 parserOptions 中,注意需要创建一个 ecmaFeatures 对象)。

你必须env.eslint像这样添加:

{
  "env": {
    "es6": true
  },
  "extends": [
    "eslint:recommended",
    "google"
  ],
  "parserOptions": {
    "ecmaVersion": 9,
    "sourceType": "module"
  }
}

我遇到过同样的问题。将节点更新到版本 8+ 应该可以修复它
