Has anyone received this 'postinstall' error with Electron on Mac Sierra?

I've tried installing Electron 5 times. Initially, it hung for ages, so I took down the VPN. Then, I get this. Does anyone know what to do? My version of node.js is straight off of their site.

Failed at the electron@1.6.8 postinstall script 'node install.js'.
