Unknown option: base.main

[zeke]

This seems related to https://github.com/paulcbetts/electron-prebuilt-compile/issues/7 in that npm start throws an error, but electron . does not.

$ npm ls electron-prebuilt-compile

$ cat main.js                     
const {app, BrowserWindow} = require('electron')
let win

app.on('ready', () => {
  let opts = {
    frame: false,
    transparent: true,
    width: 600
  }

  win = new BrowserWindow(opts)
  win.loadURL(`file://${__dirname}/app/index.html`)
})

$ npm start                       

> @ start /Users/zeke/zeke/ummoji
> electron .
