Electron-packager: Is babel supported?

[x] I have read the contribution documentation for this project.
[x] I agree to follow the code of conduct that this project follows, as appropriate.
[x] I have searched the issue tracker for an issue that matches the one I want to file, without success.

I am currently using babel in my project, including ES6 features not supported by the current version of node such as import/export. I do this by using the babel-register module when I run the app:

electron --require babel-register ./main.js

This doesn't work when using electron-packager packager though and I get syntax errors related to import when trying to run the executable:

SyntaxError: Unexpected token import

    at Module._compile (module.js:543:28)

    at Object.Module._extensions..js (module.js:580:10)

Is there anyway to tell electron-packager to run electron with the --require babel-register flag?

Console output when you run electron-packager with the environment variable DEBUG=electron-packager. Please include the stack trace if one exists.

What command line arguments are you passing? Alternatively, if you are using the API, what
parameters are you passing to the packager() function?

None

Please provide either a failing minimal testcase (with a link to the code) or detailed steps to
reproduce your problem. Using electron-quick-start
is a good starting point.

This repository recreates the issue using a simple app.

Electron Packager does not support Babel directly. You should use either electron-compile or Electron Forge, which uses both Packager and electron-compile internally.
