من اومدم پروژه (خودم) با لاراول میکس اجرا کنم خطا زیر رو داد.

سه فایل js رو که ترکیب میکنم خطا در مرورگر میده .

mix.js([
    //'resources/js/jquery.js',
    'resources/js/app.js',
    'resources/js/plugins.js',
    'resources/js/functions.js',
],'public/js/main.js');

گویا مشکل از فایل plugins.js که با خود node تداخل داره. اگر فایل‌ها مستقیم در public بذارم سایت بالا میاد

لطفا راهنمایی کنید.

Uncaught Error: Module build failed (from ./node_modules/babel-loader/lib/index.js):
