npm run prod doesn't enable production mode on vue js

Issue

I’m using Laravel with Vuejs. I wanted to publish my website but I keep getting this message in the browser console.

You are running Vue in development mode.
Make sure to turn on production mode when deploying for production.
See more tips at https://vuejs.org/guide/deployment.html

I executed npm run prod and cleared cache on my browser (chrome) but I still keep getting this message.
My webpack.mix.js looks like this:

const mix = require('laravel-mix');

module.exports = {
    mode: 'production',
    resolve: {
        alias: {
            vue: process.env.NODE_ENV == 'production' ? 'vue/dist/vue.min.js' : 'vue/dist/vue.js'
        }
    }
}

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css');

This is from my package.json:

 "prod": "npm run production",
 "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

This is what I get when I execute npm run prod

> @ prod /var/www/html/clash
> npm run production


> @ production /var/www/html/clash
> cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-    progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

What am I doing wrong?

Solution

I was able to solve the problem.
This was in my layout blade template:

    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>

:facepalm:

Sorry for being stupid.
