`yarn` build fails on initial install

So I tried to pull this project today and install it for the first time, and I got an error while running yarn.

Here's my node version:

> Christopher@Tamiasiii: ~/Code/reactjs.org> node --version
v10.1.0

This similar issue from mattermost seems like it was resolved by bumping the nan version.
I'd make a PR to do that but TBH I'm really out of my depth here. I can't even find where that would be done

Beginnen Sie damit, die anfängliche yarn-Installation zu reproduzieren, und untersuchen Sie den Build-Pfad von node_modules/sharp, einschließlich binding.gyp, src/common.cc und der referenzierten nan.h. Das Issue ist abgeschlossen, wenn eine saubere Installation ohne den node-gyp rebuild-Fehler unter Node 10.1.0 abgeschlossen wird.
