Javascript Export语句上的ESLint分析错误

我正在学习一门课程，作者以以下方式导出了一个组件：

export MainContainer from./Main/MainContainer'

默认的正确方法是从“/Main/MainContainer”导出{default as MainContainer}，这不是很干净。作者可以用babel eslint包实现这一点，但是在我安装了该包之后，仍然会出现lint错误

文件结构：

预期 在containers/index.js中使用“/Main/maincainer”中的

export maincainer时，没有ESlint错误。export语句应该允许config/routes.js像这样导入MainContainer：

从“../containers”导入{maincainer}

结果
ESlint错误：



containers/Main/MainContainer.js

import React from 'react'

export default class MainContainer extends React.Component {
  render () {
    return (
      <p>Hello World</p>
    )
  }
}

config/routes.js

import ReactDom from 'react-dom'
import routes from './config/routes'

ReactDom.render(
  routes,
  document.getElementById('app')
)

我已安装以下软件包：

"devDependencies": {
  "babel-core": "^6.25.0",
  "babel-eslint": "^8.0.0-alpha.15",
  "babel-loader": "^7.1.1",

npm运行lint脚本：

"lint": "eslint app/.; exit 0",

默认的正确方法是从“./Main/MainContainer”导出{default as MainContainer}

你从哪里得到的信息？根据报告，您可以：

export { MainContainer as default } from './Main/MainContainer'

或

在我的应用程序中，当我执行
eslint--init
时，我选择
json
作为选项之一

这创建了一个
.eslint.json
文件，因此我有两个eslint文件，我的原始
.eslintrc
和json版本

我相信
.json
版本覆盖了非json版本

以下是原始文件中添加的内容：


现在，我在使用时没有收到错误或警告：

从“/Main/MainContainer”导出MainContainer
从TylerMcginnis课程中，应用程序工作正常，只是ESlint。我刚刚解决了问题。发布我自己的答案，将等待反馈。
export { MainContainer as default } from './Main/MainContainer'

export default MainContainer from './Main/MainContainer'
