Yarn version issue

[morkeltry]

The "yarn-path" option has been set (in .../ui/.yarnrc.yml), but the specified location doesn't exist

Cannot find module '...ui/.yarn/plugins/...'
Require stack:
- .../yarn/.../yarn.js

Problem:

We are running different yarn versions but one is pinned in ui/.yarnrc.yml

Solution:

mv .yarnrc.yml .yarnrc.yml.old
yarn set version berry

Add the lines from .yarnrc.yml.old to .yarnrc.yml, except the yarnPath (keep the new line)

yarn install

Commit.

In .gitignore,
uncomment yrarn related lines:

**/.yarn/*
!.yarn/patches
!.yarn/releases
!.yarn/plugins
!.yarn/sdks
!.yarn/versions
.pnp.*
# .eslintcache
.vscode/**
