Solution to 'Uncaught error' - when trying to use Vue JS with Laravel?

I am trying to create my first Vue component to couple with my laravel mvc application. It's simply a component to use in my 'welcome.blade.php' file.
However, I am getting the following javascript error message in my console, when trying to view the page, and a blank screen:
app.js:96 Uncaught Error: Module build failed (from ./node_modules/babel-loader/lib/index.js):

This happens after completing the following steps to install Vue:
Navigate to laravel project root and run 'npm install'.
-Creating the following template:
<template>
<div class="flex-center position-ref full-height">
<div class="content">
<div class="title m-b-md">
Welcome to Vue.js on Laravel
</div>
<div class="links">
View Laravel Docs
View Vue Docs
Watch Videos
</div>
</div>
</div>
</template>
<script>
export default {}
</script>
Updating my resources\js\app.js file to include the following:
require('./bootstrap');
window.Vue = require('vue');
Vue.component('welcome', require('./components/Welcome.vue'));
const app = new Vue({
el: '#app'
});
Placing the component inside of my resources/views/welcome.blade.php file:
<title>Laravel</title>
[...]
Adding a welcome route in laravel:
Route::get('/welcome', ['as' => 'welcome.index', 'uses' => 'home_controller#welcome']);
If anyone was able to suggest a step that I might be missing, that would be absolutely super.

node-7z and xml2json conflict

in node.js,
I have problem when import both packages (node-7z and xml2json),
I have some function that no one calls it ("dummy"),
import { extractFull } from 'node-7z'
const xml2json = require('xml2json');
function dummy(){
const myStream = extractFull('./zip/myfile.7z', './unzipped/')
}
and I get the following error

*if I comment the code inside "dummy" function I dont get any error
*if I comment the line of require "xml2json" I dont get any error
why I have this problem and why how does the code in "dummy" function affect me if no one calls this function?
Thanks

https://github.com/quentinrossetti/node-7z according to this link you shoud pass an object with extractFull function for example
import Seven from 'node-7z'
const myStream = Seven.extractFull('./archive.7z', './output/dir/', {
$progress: true
});

What is the right regex pattern for ignore in #babel/register

I am running mocha on some React components that contain openlayers, the new update ol modules are all written only in ES6 and they have to be transpiled before being passed to mocha for testing.
I am using #babel/register and I am requiring a babel-register.js file in which I require #babel/register and input all the options and presets/plugins. I does not transpile and I get the error you will see down below. All I would like is requiring only the node_modules/ol and recursively all files and subfolders to transpile is the regex correct? Is there anything else wrong? My babel-register.js is as follows:
require("#babel/polyfill");
require("#babel/register")({
ignore: [
// When a file path matches this regex then it is **not** compiled
'node_modules/(?!(ol)/)'
],
presets : ["react-app", "#babel/preset-env"],
plugins : [
"#babel/plugin-transform-modules-commonjs",
"inline-react-svg",
"#babel/plugin-syntax-dynamic-import",
"#babel/plugin-transform-runtime"
],
//root: __dirname,
extensions: [".es6", ".es", ".jsx", ".js", ".mjs"],
// Setting this to false will disable the cache.
cache: false,
});
Below is the error message I get from transiplation (I am not sure is because of regex):

So, thanks to #Thomas Skubicki, the regex slashes had to be escaped, two more slashes had to be put at the beginning and end of the reg expression and single quotes had to be removed, this is the correct working version of the babel-register.js file.
require("#babel/polyfill");
require("#babel/register")({
// Array of ignore conditions, either a regex or a function. (Optional)
ignore: [
// When a file path matches this regex then it is **not** compiled
/node_modules\/(?!(ol)\/)/
// The file's path is also passed to any ignore functions. It will
// **not** be compiled if `true` is returned.
//function(filepath) {
//return filepath !== "/path/to/es6-file.js";
//},
],
presets : ["react-app"],
plugins : [
"#babel/plugin-transform-modules-commonjs",
"inline-react-svg",
],
//root: __dirname,
// Optional only regex - if any filenames **don't** match this regex then they
// aren't compiled
//only: /my_es6_folder/,
// Setting this will remove the currently hooked extensions of `.es6`, `.es`, `.jsx`, `.mjs`
// and .js so you'll have to add them back if you want them to be used again.
extensions: [".es6", ".es", ".jsx", ".js", ".mjs"],
// Setting this to false will disable the cache.
cache: false,
});

Those forward slashes in that regex may need to be escaped
'node_modules\/(?!(ol)\/)'
That regex throws errors in regex101.com
