Hello,
We have been using Quasar for a few days and today resolved to ensure we are using the latest packages.
The difficulty that has arisen is that, beginning with an updated macOS High Sierra install on a macbook pro, and what we assume to be the latest packages, we end up with a project where running quasar build results in expected behavior (a dist/ directory where we can run python -m SimpleHTTPServer and subsequently see things work locally), while running quasar dev or quasar dev --mode electron in contrast, always appears to compile fine and start the development web server or launch electron app, only to effectively serve a blank page with no error in the console or the window wherein we ran quasar dev:

↑ at this point, visiting Firefox in firefox 62.0.2 with a default about:config results in a blank page with nothing in the developer console and nothing in the terminal window managing quasar dev, while, repeating myself quasar build works OK.
Vue ff addon does not recognize the final result:

Any guidance greatly appreciated and thanks in advance.
