npm install fails with error C2373 with vs2015 update 3

This error stays in relation with npm, node-gyp and Visual Studio 2015 and is already fixed in node-gyp@3.4.0, but npm is still pointing to an old version. As I workaround I can propose this:

1. Go to your folder where npm is installed, e.g.:
   C:\Program Files\nodejs\node_modules\npm

2. Open: package.json

3. Remove entry for node-gyp in bundleDependencies

4. Bump version number to 3.4.0 for node-gyp in dependencies

5. Make a npm i in this directory to install node-gyp@3.4.0 to fix the problem
