npm run watch .js error file

See original GitHub issue

When I run command “npm run watch” or “npm run watch-poll”, the script generates a bugged .js file, and the browser console shows “Uncaught SyntaxError: Invalid or unexpected token”.

If I try to open the js file with Sublime Text (Finder show me Zero KB), seems that the script falls in a never ending loop writing in the js file null and after the compiled js script, null and so on…

No problem running the “npm run watch” with only the scss files or, with the js, running “npm run dev”.

Here’s my configs:

Node: 8.1.4 NPM: 5.5.1 Laravel mix: 1.5.0

Webpack.mix.js:

const {mix} = require('laravel-mix');
const dotenv = require('dotenv-webpack');

mix.webpackConfig({
    plugins: [
        new dotenv({
            path: './.env', // Path to .env file (this is the default)
            safe: true // load .env.example (defaults to "false" which does not use dotenv-safe)
        })
    ]
})
    .js('./resources/assets/javascripts/app.js', './public/assets/javascripts/web.min.js')
    .sass('./resources/assets/stylesheets/main.scss', './public/assets/stylesheets/main.min.css')
    .scripts([
            './public/assets/javascripts/web.min.js',
            './node_modules/jquery-migrate/dist/jquery-migrate.min.js',
            './node_modules/jquery.stellar/jquery.stellar.js'
        ], './public/assets/javascripts/web.min.js'
    )
    .extract([
        'axios',
        'jquery',
        'lodash',
        'vue'
    ]);
