Node-gyp failures in sfacts/lowdown dependency in Node 4+

See original GitHub issue

Posted this to sfacts repo but there doesn’t seem to be much activity over there.

Installing on Mac OS 10.11 with Node 4.1.2 and npm 2.14.4 fails due to an outdated dependency (leveldown) in sfacts. This, in turn, is referencing an old node-gyp, which does not work with node 4.1.2. (Or at least my 4.1.2).

The leveldown dependency in sfacts is at ^0.10.2, meaning it will install 0.10.5. The latest leveldown is 1.4.2. The latest works fine for me, as does latest node-gyp.

Is anyone else experiencing this problem?

Sorry for the cross-posting, but didn’t seem like the other issue was going to be addressed via the sfacts repo.
