New install yarn dev loads blank white frame

[timmeade]

Just forked, pulled down and yarn install.
A ton of warnings.

yarn dev

I get a blank white window.
In console I see:

Not allowed to load local resource: file:///Users/tim/src/lab/reactron/app/build/index.html

Simple google search seems to be something with webpack. Digging further now.

Ok . fix is to change in app/project.json

"main": "./electron/main.prod.js",

to

"main": "./electron/main.dev.js",

Shouldn't this work automaticatlly depending on build?
