Using an incorrect version number, doesn't log a warning

Maybe needs an option like debug: true

I was trying to use an incorrect version of Electron (0.35.1 instead of 0.35.0). Nothing warn me that it was incorrect.

This is strange. Given this here your build should've reported an error. What did you observe?

Very strange. It shows the progress bar and actually builds the .app file for Mac. When I open that file (built with a non-existent version of Electron), it shows this alert box:

You can’t open the application “raster.app” because PowerPC applications are no longer supported.

When an existent version of Electron is used, there is no problem.
