Gatsby failing production build

Recently, Gatsby started failing to build a production version of the site. Development version builds fine.

It seems to be some Babel issue but I can't figure out what it is. I've upgraded everything, deleted the node_modules folder and yarn.lock but after building everything afresh again it fails the same way.

I'm not particularly familiar with the inner workings Babel so I'm guessing this is something to do with the Babel settings shipped with Gatsby?

Solution

I'm not sure if this can help for local builds, but I had the same issue when deploying on Netlify today and I have been able to solve the issue by switching to npm.

Here is the steps I followed:

removed yarn.lock and old package-lock.json
added yarn.lock, removed package-lock.json from .gitignore
removed node_modules folder
re-installed dependencies with npm
run build command with npm
