NativeScript WebView正在src文档中加载本地资源

我正在加载一个本地html文件作为NativeScript WebView组件的src。html文件中包含的脚本标记引用了javascript文件，这些文件也是本地资源(绑定在应用程序中(。html文件加载到WebView中很好，但引用的脚本文件(mylib.js(没有。

我怀疑这是一个路径问题，但我几乎尝试了我能想到的每一种变体，但都无济于事。

我的项目实际上是一个NativeScript Vue项目，如下所示：

App.vue

<template>
    <Page @loaded="onPageLoaded">
        <ActionBar title="Welcome to WebView"/>
        <GridLayout>
            <WebView ref="myWebView" row="0" col="0" 
            :src="filePath" @loadFinished="onWebViewLoaded" />
        </GridLayout>
    </Page>
</template>
<script>
import * as fs from "tns-core-modules/file-system"
import * as utils from "utils/utils"
  export default {
    data() {
      return {
        filePath: ''
      }
    },
    methods: {
        onPageLoaded () {
            this.setLocalIndexFilePath()
        },
        onWebViewLoaded (event) {
            if (event.error) { 
                console.log(error)
            } else {
                console.log('webview loaded')
            }
        },
        setLocalIndexFilePath () {
            const deviceName = 
            utils.ios.getter(UIDevice, UIDevice.currentDevice).name
            // iPhone 6 is the name of my simulator
            if (deviceName == 'iPhone 6') {
                const webViewSRC = 
                encodeURI(`${fs.knownFolders.currentApp().path}/www/index.html`)
                this.filePath =  webViewSRC
                console.log(webViewSRC)
            } else {
                this.filePath = "~/www/index.html"
            }
        }
    }
  }
</script>

index.html

<!doctype html>
<head>
    <script src="./mylib.js" type="text/javascript"></script>
    <script type="text/javascript">
        function onBodyLoaded() {
            var msg = document.getElementById('msg');
            msg.insertAdjacentHTML('beforeend', '<br />body loaded!');
        }
        function onLocalButtonClicked() {
            var msg = document.getElementById('msg');
            msg.insertAdjacentHTML('beforeend', '<br />local: You clicked button!');
        }
    </script>
</head>
<html>
    <body onload="onBodyLoaded()">
      <Button onclick="onLocalButtonClicked()">Click Me</Button>
      <Button onclick="onButtonClicked()">Click Me to test external js</Button>
      <p id="msg">Debug:</p> 
    </body>
</html>

mylib.js

// This function never gets called
function onButtonClicked() {
  var msg = document.getElementById('msg');
  msg.insertAdjacentHTML('beforeend', '<br />external js file: You clicked button!');
}

webpack.config.sys

... 
// Copy assets to out dir. Add your own globs as needed.
new CopyWebpackPlugin([
    { from: "fonts/**" },
    { from: "**/*.+(jpg|png)" },
    { from: "assets/**/*" },
    { from: "www/**/*" }, 
...

这是iOS的已知问题。你可以尝试一个补丁，我在Playground中针对类似的问题实现了同样的补丁，它也适用于Vue。
