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relating to setting icons using electron-packager but none of the answers have worked for me – maybe the answers are out of date or not clear – but I need to ask again.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

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

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

Even with an updated path, I'm still not getting the icon coming through building for mac – Kraft

I tried this command for my application and ended up with the error Packaging app for platform win32 x64 using electron v4.0.5 rcedit.exe failed with exit code 1. Cannot open icon file '.' Fatal error: Unable to set icon – Histrionism

@JacobNelson I'll need a bit more detail than that to fix your problem. Can you post a seperate question – Mutual

Answer 2

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.

[1] Icon path: The icon path is not relative to the project directory, but to the current location. (For me, the problem was that I assumed the former, as I thought it made sense with less redundancy.) In any case, one has to run either:

electron-packager projectDirPath outputName ... --icon=projectDirPath/iconPath/icon.png

Or if you are in the project directory:

electron-packager . outputName ... --icon=iconPath/icon.png

[2] Icon format: For macOS, both icon.png and icon.icns is accepted. For Windows, both icon.png and icon.ico is accepted.

[3] Icon size: For macOS, the dimensions must be at least 512x512px. For Windows, the dimensions must be at least 256x256px.
