That one is still my main problem. I know, I know, Windows is evil and so on, but our customers use it. We are remarkably free in choosing our tools or whatever, but Windows is usually a constant (Intranet environments) and every day I crash against the absolute "Windows is a second class platform" problem of NPM modules. For an environment which is supposedly platform-agnostic the amount of "only on Unix" is astonishing.
Maybe that you use a lot of modules with c dependencies?
