Have you tried npm rebuild?

[kjata30]

No, but I ended up just reverting to nodejs 0.12.x and it works just fine.

I do have this issue, but I'm a bit confused about versioning and node. I think I have the latest, but node -v reports as v7.4.0. I did do a rebuild.

Should I upgrade something, or actually downgrade?

[bhebing]

OK, so the versioning is clear now :)

Anyway, issue is on v7.4.0, but on the v6 LTS release.

@bhebing Downgrading to node 0.12.18 solved this issue for me.
