hi kimee, welcome! Looking at your build log, I wonder if this is not so much a netlify issue but a gatsby one as the call to that package seems to come from that install.
Are you seeing the issue locally as well? That’s always the first thing to check. Even if you have updated node locally, we may be hanging on to an older version on our servers. I think i’d recommend you try clear cache and deploy.
This Common Issue contains a ton of useful debugging tips that might help.
if not, please do share your package.json as well when you post again.
