Error running npm-install

Today, I started getting errors when running npm install for my web application. I seem to have traced it to npm-gyp. Here is what I get when I try to install it:

$ npm install node-gyp@3.6.1

> microtime@2.1.3 install C:\Development\node_modules\microtime
> node-gyp rebuild
