[Bug]: `yarn rw dev` fails on yarn 4 node 20 about redwood HOT 5 CLOSED

Downgraded to node 18, but kept yarn 4. Still get the same error

from redwood.

Went back up to node 20, but downgraded yarn to 3.7.0. Now everything works.
yarn set version 3 is the workaround for this issue for now ✅

from redwood.

Another thing that works is:

❯ yarn create redwood-app -y rw-yarn-4
❯ cd rw-yarn-4
❯ yarn set version 4
❯ yarn install
❯ yarn rw dev

That is, updating the project itself to use yarn 4 makes it all work.

(Do note that it still complains about fsevents when installing, but doesn't error out when running)

To me this is starting to look like a bug with yarn. Shouldn't it use yarn 3 inside the project directory since we have "packageManager": "[email protected]"? I'll try to get @jtoar's eyes on this too. He has more experience with yarn than I do

from redwood.

Fixed by updating our documentation in #9579
