Electron-packager not setting icons

Question

There are lots of questions relating to setting icons using electron-packager but none of the answers have worked for me – maybe the answers are out of date or not clear – but I need to ask again.

I am building on OSX for OSX & Windows. I've tried at least 20 variations on specifying the icon for electron-packager (the full cmd set is below). I've tried referencing icons withing the app folder (app/assets/WIN_logo.icns) as well as in an "icons" folder at the project root (icons/assets/WIN_logo.icns); I've tried using quotation marks, leaving off the extension and other stuff I can't even recall.

So please, can someone tell me, given the directory structure below, how I specify the icon for electron-packager to use.

-icon=assets/WIN_logo.icns
-icon=assets/WIN_logo.ico

  "package-mac": "electron-packager . --overwrite --tmpdir=false --platform=darwin --arch=x64  --prune=true --out=release-builds -icon=assets/WIN_logo.icns",
  "package-win": "electron-packager . --overwrite --tmpdir=false --platform=win32 --arch=ia32 --asar=true  --prune=true --out=release-builds -icon=assets/WIN_logo.ico"

Answer 1

For mac

1/ verify that the name of the icon is icon.icns 2/ verify that the icon size is at least 512x512px 3/ change --out=release-builds by --out=build

For windows

1/ verify that the name of the icon is icon.ico 2/ verify that the icon size is at least 256x256px 3/ change --out=release-builds by --out=build

these steps works for me.

Answer 2

Change -icon=assets/... to --icon=./assets/...

The icon argument should have two hyphens at the start and the path should start with ./.
