Reading Tailwind config file fails silently

[designbyjr]

const mix = require('laravel-mix'); require('mix-tailwindcss'); mix.js('resources/js/app.js', 'public/js') .sass('resources/sass/app.scss', 'public/css') .tailwind('dsdsjsdisdio');
The above code should fail, but it does not. Currently my npm verson is 6.3.0.
I got the latest installation from npm i mix-tailwindcss.
