I can not get/retry the working assembly webpack

[Volodymyr]

Hi all!
Rechecked package versions, no deviations.
The nmp worked without errors.

The resulting file does not work correctly.
VUE stops working

To expand the functionality I wanted to add a Vue-component.
But here I can not get the source.

Hi @Volodymyr

Please run following commands at root of these packages. - Shop, Admin and Ui.

1. npm run watch
2. npm run watch-poll
3. npm run prod

Thanks

I do not work for us directly with default. I have theme Custom configured and the changes are only for the shop.
I found the reason why the assembled package did not work. Many may have encountered - in the debugger does not work
And everyone is looking for a reason.
The problem was in the file resources/assets/js/app.js

It was necessary to explicitly declare variables in 1, 9 lines.
