"npm run dist" fails when behind a proxy

[stepbeta]

• System: Windows 10 Home x64
• electron: 1.3.5
• node: 5.8.0
• npm: 3.7.1
• electron-builder: 6.4.1
• target platform: Windows

I'm trying to build an application, following the steps outlined here.
I am behind an enterprise proxy, which gives me headaches every day, but I managed to get npm working, using the following configs:

C:\path>npm config list
; cli configs
user-agent = "npm/3.7.1 node/v5.8.0 win32 x64"

http-proxy = "http://user:pwd@adress:port/"
https-proxy = "http://user:pwd@adress:port/"
proxy = "http://user:pwd@adress:port/"
registry = "http://registry.npmjs.org/"
strict-ssl = false

when executing npm run dist, though, these settings are ignored and the following errors are produced on console:

C:\Users\Stefano>npm run dist

Derris@0.1.0 dist C:\path
build
