Error installing appworks-cli: Failed at the node-sass@3.8.0 postinstall script.

I'm having problems installing appworks-cli. I've tried both using npm and installing it from the clone git repository. The issue is installing node-sass@3.8.0. I can install the latest node-sass, but 3.8.0 won't install.

Cannot download "https://github.com/sass/node-sass/releases/download/v3.8.0/win3
2-x64-57_binding.node":

HTTP error 404 Not Found

Is there a way to use a later build of node-sass for appworks?
