ERROR in build.js from UglifyJs

[alcnsahin]

Hello,

I am getting the following error while building a Vue.js application. How to fix it?

ERROR in build.js from UglifyJs Unexpected token: punc ()) [./node_modules/vue-toast-notification/dist/index.min.js:1,225][build.js:23778,189] npm ERR! code ELIFECYCLE npm ERR! errno 2 npm ERR! drmon-frontend@1.0.0 build: cross-env NODE_ENV=production webpack --progress --hide-modules npm ERR! Exit status 2

Thanks.

Hey,

What is your laravel-mix version?
Looks like you are using quite old version which is using UglifyJs rather than TerserJS

UglifyJs does not support parsing ES6 syntax.
Upgrade you laravel-mix to v5 or above which is using TerserJS
