Let me know if there's a better channel to post this question. If I were wanting to use a different version of yarn package manager, how would I point Pants to use a binary hosted at an endpoint such as

<https://github.com/yarnpkg/yarn/releases/download/<version>/yarn-<version>.tar.gz>

, where the

<version>

is specified in the Pants options like so?

binaries_baseurls: +[
    '<https://binaries.pantsbuild.org>',
    '<https://github.com/yarnpkg/yarn/releases/download>',
  ]

[yarnpkg-distribution]
version: v1.17.3

The root of the issue is that Pants is expecting a specific folder structure

<https://github.com/yarnpkg/yarn/releases/download/bin/yarnpkg/mac/10.13/v1.17.3/yarnpkg.tar.gz>

, and I'm wondering if there is a way to circumvent that.

Hm… not sure if there’s a way to pin that in the way you’re looking to, seems like we could update

YarnpkgDistribution

similar to how we did for

node

in https://github.com/pantsbuild/pants/commit/6739a81b6008274bfb4abd3436d9adb543a19e5a to permit it though

Yeah, similar functionality to that would work! Should I open a feature request / enhancement? And as a workaround, would using an internal binaries repo with the correct folder structure that we point to work or can you think of any complications to to that?

Yeah I’ve seen that work (patching the

binaries

repo for the a version not currently supported and point to that in your

pants.ini

)

My error is below and occurs when I

bundle

I was at Pants v1.11.0, but I also tried at v1.18.0.dev0 and got the same error. I’m also setting the following config for node:

[node-distribution.bundle.node]
version: v12.7.0
package_manager: yarn
eslint_config: app/web/.eslintrc

Got it, thanks. I’m now seeing it elsewhere - curious that it didn’t cause issue on my mac

That was fast, and looks like exactly what I need. 😄 Thank you!
