Error: Uncaught Exception: Error: Unable to find a valid app at Object.<anonymous> ...

I have been trying to package up my app with no luck. At first I was trying to use electron-packager to package up my whole project without ng build, but this gave me a static index.html, breaking my angular 2 app. Now I am using electron-packager on my dist folder after using ng build and I am getting this error:

Uncaught Exception:
Error: Unable to find a valid app
    at Object.<anonymous> .../App.app/Contents/Resources/electron.asar/browser/init.js:121:9)
    at Module._compile (module.js:556:32)
    at Object.Module._extensions..js (module.js:565:10)
    at Module.load (module.js:473:32)

    at run (bootstrap_node.js:402:7)
    at startup (bootstrap_node.js:157:9)
    at bootstrap_node.js:521:3

I am passing:

"macBuild":"electron-packager ./dist App --out=releases/ --platform=darwin --arch=all --ignore=electron-packager --icon=icon.icns --overwrite --asar",

This also deletes my node_modules for some reason after it builds.

Originally I was passing:

    "macBuild":"electron-packager . App --out=releases/ --platform=darwin --arch=all --ignore=electron-packager --icon=icon.icns --overwrite --asar",

But that gave me a static index

If you're having issues with using Angular 2 with Electron I'd recommend using electron-forge.

It has built in support for Angular 2 (thanks to electron-compile), you can see an example here

https://github.com/electron-userland/forge-examples/tree/master/angular2

It should handle all your troubles for you while still using electron-packager under the hood 👍

electron-forge import should go most of the way to getting your app working with forge as well 😄

I just attempted electron-forge import, but it failed when trying to install electron-prebuilt-compile, not sure if I should continue messing with it or not

Please file a bug in the Electron Forge project (I think it has to do with the version of Electron you're using). With regards to your Electron Packager problem, my suspicion is that you're not setting main in package.json to an appropriate value.

An unhandled error has occurred inside Forge:

Yup, I've notified the maintainer of electron-prebuilt-compile.

Okay so should I continue to use this module or...??

Use 1.4.12 temporarily.
