Yarn Build Error: Chunk.entrypoints: Use Chunks.groupsIterable and filter by instanceof Entrypoint instead

Hi all. I’ve just gone from sage 8 to my first project using sage 9. I’m having a nightmare with yarn. When I run yarn build I get the following output:

I’m really not sure how to resolve this as I’ve never used yarn before. Can anyone provide a clue as to how to solve this error?

Thanks in advance!

Have you tried Google? The first result for your error is this GitHub issue that offers some insight: https://github.com/webpack/webpack/issues/6568

Is this a fresh Sage installation? Have you added or removed anything? It looks like this might be related to webpack 4, which Sage doesn’t support yet: https://github.com/roots/sage/issues/2102

Humm, it’s a fresh install. It seems to insist on using webpack 4… Oh well, I might just scrap it and try again.

Not sure what happened but I just started again with another fresh install and everything worked just fine.

I was having the exact same issue. What fixed it for me was to first run npm install from the theme directory. After that I can run yarn build and it will succceed.
