eslint 在命名导出时抛出解析错误意外标记

eslint throws parsing error unexpected token on named export

我有一个 index.js 文件,其中包含以下命名导出。

export Main from './Main/Main'

然而,eslint 不喜欢这样并抛出错误

Parsing error: Unexpected token Main

我不确定为什么应用程序运行正常,我相信这是有效的语法。

我的 .eslintrc 文件如下所示

{
  env: {
    es6: true,
    browser: true
  },
  parserOptions: {
    ecmaVersion: 6,
    sourceType: "module",
    ecmaFeatures: {
      jsx: true,
      experimentalObjectRestSpread: true
    }
  },
  plugins: [
    "react",
  ],
  extends: ["eslint:recommended", "plugin:react/recommended", "standard"],
  "rules": {
    "comma-dangle" : [2, "always-multiline"],
    "semi": [2, "never"],
    "no-extra-semi": 2,
    "jsx-quotes": [2, "prefer-single"],
    "react/jsx-boolean-value": [2, "always"],
    "react/jsx-closing-bracket-location": [2, {selfClosing: "after-props", nonEmpty: "after-props"}],
    "react/jsx-curly-spacing": [2, "never", {"allowMultiline": false}],
    "react/jsx-max-props-per-line": [2, {maximum: 3}],
    "react/jsx-no-literals": 2,
    "react/sort-prop-types": 2,
    "react/self-closing-comp": 2,
    "react/sort-comp": 2
  },
}

想通了。这是一个实验性功能,所以我需要启用 babel-eslint 作为我的 eslint 解析器。

现在我的 .eslintrc 看起来像这样

{
  parser: "babel-eslint",
  env: {
    es6: true,
    browser: true
  },
  parserOptions: {
    ecmaVersion: 6,
    sourceType: "module",
    ecmaFeatures: {
      jsx: true,
      experimentalObjectRestSpread: true
    }
  },
  plugins: [
    "react",
  ],
  extends: ["eslint:recommended", "plugin:react/recommended", "standard"],
  "rules": {
    "comma-dangle" : [2, "always-multiline"],
    "semi": [2, "never"],
    "no-extra-semi": 2,
    "jsx-quotes": [2, "prefer-single"],
    "react/jsx-boolean-value": [2, "always"],
    "react/jsx-closing-bracket-location": [2, {selfClosing: "after-props", nonEmpty: "after-props"}],
    "react/jsx-curly-spacing": [2, "never", {"allowMultiline": false}],
    "react/jsx-max-props-per-line": [2, {maximum: 3}],
    "react/jsx-no-literals": 2,
    "react/sort-prop-types": 2,
    "react/self-closing-comp": 2,
    "react/sort-comp": 2
  },
}

由于不同的原因我得到了同样的错误,这里是我出错的地方:

如果你在 atom 包开发中使用 babel,babel 由每个文件开头的 use babel 激活。

use babel,就像 use strict 需要放在文件的最开头一样!在它前面的 space 会停用它,然后 js 引擎会绊倒您的导出语句或类似的```意外的令牌导出````。

错误:

use babel import { bla } from 'blub'

正确:

use babel import { bla } from 'blub'
