Hi, I am trying to get F8 app to build for Windows Phone. When running npm install, I get the following error:

After I ran it as administrator, it managed to create npm-debug.log (attached)
npm-debug.zip
Any idea what the problem could be?
N.B: I am running that on a Windows 10 machine and I have node 6.2.1 and npm 3.9.3 (as shown in the attached screenshot).
Any help would be appreciated,
Hisham
