../node_modules/nan/nan.h:53:10: fatal error: 'uv.h' file not found

[saper]

When building node-sass (v4.13.0) with the node engine that does not bundle uv we may get
a problem with not finding <uv.h> in the right place.

@saper is this specific to our setup or something general with Node 13? I know FreeBSD was dropped from the support tiers by the Node Build WG, so they may not have tested at all there

[saper]

This is a general problem, not specific to node 13.

I logged this here for now, but I suspect it is something that should be fixed in node-gyp. Interestingly, node says that /usr/local/include should be added to include_dirs.

Might be related to nodejs/node-gyp#1264
