node-gyp rebuild fails in VS2015 due to wrong path

See original GitHub issue

Package restore in Visual Studio 2015 fails with the following:

Looks like the file path to node-gyp.js is wrong - I believe it should be:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\External\npm\node_modules\node-gyp\bin\node-gyp.js

This may be a result of installing the lates Node.js Tools for Visual Studio (I’m not sure this is the cause though) https://www.visualstudio.com/en-us/features/node-js-vs.aspx
