Build fails when trying to use latest Yarn v 3.0.2

I am trying to upgrade my project to use the latest yarn (v3.0.2) and I see Netlify build is failing.

I have figured out that the error " Unknown Syntax Error: Unsupported option name ("–no-ignore-optional")." occurs because Yarn 3.0.2 no longer supports the --no-ignore-optional option. I’m not sure how Netlify is using this flag or where to unset it in Netlify.

Here is a GitHub issue on yarn berry that says yarn no longer supports this option. What happen to --ignore-optional? · Discussion #2412 · yarnpkg/berry · GitHub

I was able to reproduce this issue on my local system with yarn 3.0.2 by running yarn install --ignore-optional

Now, where can I change this in Netlify so that option is not used during Netlify build?

Hi @SapneshNaik,

I’m a a little confused.

Here I see Yarn 1 is being installed.

But suddenly, I see Yarn 3 being used.

How’s that happening?

Same happens to me.
It seems to try and find yarn at

> Failed to download https://yarnpkg.com/downloads/3.0.2/yarn-v3.0.2.tar.gz

But it’s not there.

I am switching to classic v1.22.15 for now.

Hi @ilyafefelov,

Your issue seems different than the actual post.

However, based on this: Yarn 3 workspaces are not cached at all · Issue #615 · netlify/build-image · GitHub, Yarn 3.0.1 works. Does that work for you?
