Based on this: build-image/run-build-functions.sh at focal · netlify/build-image · GitHub, I don’t think we’re actually using the flag. I’m also getting it confirmed with the developers, but at the moment I’m not seeing us using
ignore-optional flag by default anywhere in the code-base.
Are you seeing it cause problems?
Hmm that’s weird. Yeah I think
typedoc is not installed so I strongly suspect an issue with optional dependencies.
I’ve filed an issue here:
But to help with the investigation, could you share a repo with reproduction?
We heard back from the team and found out that
ignore-optional flag is only set on Yarn version
0.18.1. You can see more details about it in the above issue. So if you’re seeing this issue, we’d ned a reproduction to test.
