electron-vue webview js 文件打包出的代码浏览器不能识别?

Question

想在electron-vue 项目中实现打印功能，想采用渲染进程与webview通信的方式实现，webview也是用vue写，现在碰到一个问题，webview 的js 打包出来后是module.exports = ........这样的代码，浏览器环境识别不了

webview 的js 代码 print.js

import Vue from 'vue'
import axios from 'axios'

import Pw from './pw'
// import router from './router'
// import store from './store'

if (!process.env.IS_WEB) Vue.use(require('vue-electron'))
Vue.http = Vue.prototype.$http = axios
Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
    components: { Pw },
    // router,
    // store,
    template: '<Pw/>'
}).$mount('#print')

print.js 中 引入的 vue 代码

<template>
    <div>this is vue webvue</div>
</template>

<script>
    export default {
        name: 'pw'
    }
</script>

<style>
    /* CSS */
</style>

webview 的打包代码 webpack.webview.config.js

'use strict'

process.env.BABEL_ENV = 'renderer'

const path = require('path')
const { dependencies } = require('../package.json')
const webpack = require('webpack')

const BabiliWebpackPlugin = require('babili-webpack-plugin')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const { VueLoaderPlugin } = require('vue-loader')

let whiteListedModules = ['vue']

let webviewConfig = {

module.exports = webviewConfig

babel 配置文件 .babelrc

{
  "presets": ["babel-preset-env"]
}

打包出来的文件是

module.exports=function(n){  ...........  }

报错 module is not defined

如何让这个webview 的js 代码正确打包成让浏览器可识别的js
