It is a bug that seems to keep persisting. Delete your cache before you run gatsby build.

Worked like a charm. Thanks.

I do experience the same bug very often, maybe someone should investigate ?

Yeah deleting .cache isn't a good solution — the .cache has to be 100% reliable so let's figure out what the bug is.
@vpicone excited to have a nice reproducible example! Except there seems to be some files missing from your repo? Tried installing and running it and got this error:
These relative modules were not found:
* ../components/github.svg in ./src/pages/connect.js
* ../components/linkedin.svg in ./src/pages/connect.js
* ../components/twitter.svg in ./src/pages/connect.js
* ./tint-drop.svg in ./src/components/Navbar.js

People in this thread — how often are you seeing errors like this now? Feels like we've made a lot of improvements.

Closing this issue as it's fairly old and we have far too many open issues! If you have additional problems in this area, please open a new issue!
