Having trouble with the `npm run dev` command in a Laravel project? You may be encountering a `TypeError: program.parseAsync is not

Recently, I integrated Vue.js into my ongoing Laravel project using npm to delve into front-end development with the framework.

Following the installation, the instructions guided me to execute npm run dev in order to visualize the modifications made in

../resources/js/components/Posts/Index.vue
and
../resources/js/components/app.js
. However, upon running npm run dev, an extensive log of errors surfaced, leaving me perplexed as to what was causing the issue.
