Electron Packer hangs... produces this output and then nothing happens:

I found some similar problems in the electron issue list:

https://github.com/electron-userland/electron-packager/issues?q=is%3Aissue+hangs+is%3Aclosed

I saw this "error" also on appveyor yesterday. I'm not sure why, but I can't build the osx package on my windows device.

had the same issue with the "Start npm install..." maybe we ignore some error code and get stuck?

It seems, when the npm_modules are not there or the electron packer is not "installed" with the correct dependencies, then this happens

if the next commit doesnt solve the problem, maybe the /c switch is needed https://stackoverflow.com/questions/4291912/process-start-how-to-get-the-output
