Brett,
I installed all the VS2010, but was still not able to build the package.
Then I discovered the --msvs-version=2013 switch:
npm install "git+https://github.com/couchbase/couchnode.git#master" --msvs-version=2013
Now I was finally able to run the application under Node 0.12 on my Windows machine.
Thanks for your help!
Cheers,
Nils Magne
