Javascript 箭头函数转换无法传输从导入模块中导出的箭头函数，IE11中出现错误

目前，我的项目有一个问题，那就是我的箭头函数无法从我自己导入的模块进行传输。我试着用我的例子来解释：

这是我的.babelrc文件

{
  "plugins": [
    "transform-object-rest-spread",
    "transform-object-assign",
    "transform-class-properties",
    "react-html-attrs",
    "syntax-dynamic-import",
    "react-hot-loader/babel",
    "transform-es2015-arrow-functions",
    "transform-es2015-function-name",
    "transform-es2015-shorthand-properties"
  ],
  "presets": [
    [
      "env",
      {
        "targets": {
          "browsers": [
            "Chrome >= 52",
            "FireFox >= 44",
            "Safari >= 7",
            "ie >= 9",
            "last 4 Edge versions"
          ]
        },
        "useBuiltIns": true,
        "debug": true
      }
    ],
    "react",
    "es2015"
  ]
}

这是我的package.json

"devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.5",
    "babel-plugin-react-html-attrs": "^2.1.0",
    "babel-plugin-transform-class-properties": "^6.24.1",
    "babel-plugin-transform-es2015-arrow-functions": "^6.22.0",
    "babel-plugin-transform-es2015-function-name": "^6.24.1",
    "babel-plugin-transform-es2015-shorthand-properties": "^6.24.1",
    "babel-plugin-transform-object-assign": "^6.22.0",
    "babel-plugin-transform-object-rest-spread": "^6.26.0",
    "babel-preset-env": "^1.6.1",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-0": "^6.24.1",
    "babel-preset-stage-3": "^6.24.1",
    "webpack": "^3.1.0",
    "webpack-hot-middleware": "2.18.2",
    "webpack-merge": "4.1.0",
    "webpack-node-externals": "^1.7.2"
  }

这是我在webpack.config中的babel loader配置

   module: {
    rules: [
        {
            test: /\.js[x]$/,
            exclude: /(node_modules|bower_components)/,
            use: {
                loader: "babel-loader"
            }
        },
        { test: /\.(png|jpg|jpeg|gif|svg|woff|woff2|eot|ttf)$/, use: 'url-loader?limit=25000' }
    ]
}

通过这些配置，我尝试了两个示例，即当arrow函数位于根组件中时，它确实将arrow函数传输到脚本中，但当我从其他文件导入函数时，它将arrow函数导入到我的组件中，并在IE11中出错

第一个例子是工作：

import React from 'react';

const testing = data => {
    console.log(data);
    return data;
}

class App extends React.Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <div>{testing("Hi, this is testing.")}</div>
        )
    }
}

箭头函数转换不会将示例2testing.jsxtestingFunction（）转换为现代javascript

是不是我错过了什么，为我蹩脚的英语感到抱歉。 多谢各位

import React from 'react';
import testing from "./testing"

class App extends React.Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <div>{testing("Hi, this is testing.")}</div>
        )
    }
}

const testingFunction = data => {
    return data;
};

export default function testing(data){
    return testingFunction(data);
}
