'node-gyp rebuild' installation error when adding a package to meteor app in Windows 7

I was trying to add a package (mizzao:turkserver) to my Meteor application, but I kept getting this error:

mizzao:turkserver: updating npm dependencies – request, libxmljs,
validator, querystring, async, deepmerge…

While building package mizzao:turkserver:
error: couldn’t install npm package

I am developing my Meteor application on a Windows 7 machine and from what I have been able to gather from posts on forums, the error seems to be related to that fact (interaction between npm and Windows - I did not find any posts describing the same problem on Linux machines).

I’ve already tried installing the latest Python version and MS Visual Studio 2013 as suggested here: https://github.com/TooTallNate/node-gyp#installation, as well as setting some environment variables as suggested here: https://github.com/atom/atom/issues/2754. But none of those helped.

Any help would be greatly appreciated!

There’s quite a bit of setup involved, and a lot of changes seem to be in the pipeline for node-gyp

Look over this readme, it helped me quite a bit: https://github.com/nodejs/node-gyp
