I tried to run "VCBuild.exe"

My environment:

• Windows 10 Pro X64

• node v7.9.0-x64

• Visual Studio 2017

So,I've just run like this command.

 $npm install --global --production windows-build-tools

But it doesn't work. Errors are bellow:

> windows-build-tools@1.2.1 postinstall C:\Users\Josephine\AppData\Roaming\npm\n       ode_modules\windows-build-tools
> node ./lib/index.js
