Question

任何人都可以找出我如何解决棉绒错误。此代码已经过测试，可以正常工作。唯一的事情是我无法在云功能基础架构上部署它。

我确定.eslintrc文件出问题了。谁能帮我解决如何使用点差运算符的问题。

这是linter引发错误的地方：

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

这是我的.eslintrc文件：

对于后代来说，由于它具有500个视图并且没有解决方案：这对我有用-

在.eslintrc.json中更改

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

到

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

然后尝试重新部署

ESLint确实支持对象保留/扩展，但是您必须通过配置选择加入。您可以将ecmaVersion设置为2018（在parserOptions中），也可以将ecmaFeatures.experimentalObjectRestSpread设置为true（同样在parserOptions中，请注意需要创建ecmaFeatures对象）。

您必须像这样添加env.eslint：

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

我有同样的问题。将节点更新到版本8+应该可以解决
