Electron-builder causes SyntaxError: Cannot use import statement outside a module

[keechan]

I just started using electron-builder instead of electron-packager.

I have added this to my package.json:

  "main": "./src-electron/main-process/electron-main.js",
  "build": {
    "productName": "someproductname",
    "win": {
       "target": ["portable"]
    },
   "portable": {
      "artifactName": "someproductnameport.exe"
    }
  },

And in my quasar.conf.js:

      builder: {
        appId: 'com.electron.someproductname',
        nsis: {
          target: 'portable'
        }
      },

It generates the bundle ok but when I try to run it, I get this error:
import { app, BrowserWindow, nativeTheme } from 'electron'

What am I doing wrong? Thanks!

Just a hunch, have you tried using require() instead of import for this case?
