npm run build fails PS1.7

[Lukenzo]

Hello. Could anyone share working package.json and webpack.config.js files? I tried the original ones from the downloaded pack, tried ones from github repo. I tried running npm install and I also tried installed them one by one. When I run npm run build command I get this error : 

 

let config = {

Any ideas how to fix this ? PrestaShop version: 1.7.2.1

Never mind. Finally fixed it. Anyone who will encounter this error should add :

"use strict";

to wbpack.config.js

Solution for this issue I found:

Add into /themes/classic/_dev/webpack.config.js after output:

resolve: {
	preferRelative: true,
},
