White screen in stock 0.14.2 web app and derivatives

[Sfinx]

Hi,

I’m using the ncu (https://www.npmjs.com/package/npm-check-updates) to have all messy node_modules dir up to date. But if somebody will do the following:

…
npm install -g npm-check-updates
mkdir test
cd test
quasar init .
ncu -u
quasar build
…

he/she will have the :

a) broken build because of postcss-loader is > 1.3.3 (famouse 'No PostCSS Config found ’ error [https://github.com/postcss/postcss-loader/issues/204])

b) after fixing the a) - the nice blank white screen without any error because of vue-loader is > 12.2.2

The question is - how to debug white screen in this case ? Or we have to stuck inevitably with old packages ?
