alt Hacker Newsyarn pnp is currently broken on Node v25.7+;
- https://github.com/yarnpkg/berry/issues/7065
- https://github.com/nodejs/node/issues/62012
This is because yarn patches fs in order to introduce virtual file path resolution of modules in the yarn cache (which are zips), which is quite brittle and was broken by a seemingly unrelated change in 25.7.
The discussion in issue 62012 is notable - it was suggested yarn just wait for vfs to land. This is interesting to me in two ways: firstly, the node team seems quite happy for non-trivial amounts of the ecosystem to just be broken, and suggests relying on what I'm assuming will be an experimental API when it does land; secondly, it implies a lot of confidence that this feature will land before LTS.

Strong rec to choose PNPM over yarn. I just posted this in a peer comment: https://news.ycombinator.com/item?id=47415173

yarn/node relations specifically are... complicated. On display on corepack (yarn project which got bundled into official nodejs distribution) issue tracker.

This confidence is somewhat concerning. Will it get reviewed at all or has the "trust the LLM" mandate arrived at Node too now.
