Can we get clarification on what support needs to be added here? I have tested locally by commenting out the util.IsNMLinker(cwd) check, and turbo run works fine with yarn 3 and the pnp linker (monorepo with around 50 packages). I would imagine turbo prune doesn't work, but if that's the case would you be open to a pull request that moves the isNMLinker check into the prune command specifically to enable yarn pnp for run?

It looks like maybe the bin script also needs work, but that can be fixed by changing:

const turboLibDir = path.dirname(require.resolve("turbo"));

to reference package.json since the turbo package doesn't have a "main" export and the above resolve fails:

const turboLibDir = path.dirname(require.resolve("turbo/package.json"));

This is now available in turbo run for turbo@1.2+

Great news! Thanks so much for working on this.

It seems that only the node-module linker from yarn is supported (

turborepo/cli/internal/packagemanager/berry.go

Line 86 in c09cb4b

return false, fmt.Errorf("only yarn nm-linker is supported")

). This issue is related to the PnP linker so it should be re-open

Would be really nice if nodeLinker: pnp could be supported.

@jaredpalmer, As @thebanjomatic explained, looks like the yarn prune is not supported yet.
Should we follow this up in this issue or open another issue?

Hello everyone!
Is this problem with support for yarn 3 pnp being resolved somewhere else?
Or is this subject dead for now?

Is this continued at #1066 ?

Thanks!

We currently have no plans to support Yarn 3 (Berry) in PNP mode. It was never supported (in spite of the earlier mention in this thread). The path to support for this is one of two options:

1. Open a PR. We will accept this work if done by the community and maintain it in perpetuity.
2. We're corporate-sponsored OSS. If your company needs this and is a Vercel Enterprise customer reach out through your account manager and we can start a discussion.

@nathanhammond
Thank you for clarifying this matter for me!

Yarn PNP is de facto standard for monorepos. How is it possible that it's not supported?
