error This project's package.json defines "packageManager": "[email protected]". However the current global version of Yarn is 1.22.22.

Presence of the "packageManager" field indicates that the project is meant to be used with Corepack, a tool included by default with all official Node.js distributions starting from 16.9 and 14.19.
Corepack must currently be enabled by running corepack enable in your terminal. For more information, check out https://yarnpkg.com/corepack.

Hello @unbegrenzt, to use a specific version of Yarn, just uninstall the preinstalled version and install the one you need using npm.

            script: |
              sudo npm uninstall -g yarn
              npm install -g [email protected]
              yarn --version

I am not sure why the answer above is marked as correct, it doesn't work. There is no [email protected] in NPM.

npm install -g [email protected]

npm error code ETARGET
npm error notarget No matching version found for [email protected].
npm error notarget In most cases you or one of your dependencies are requesting
npm error notarget a package version that doesn't exist.

You can check the existing yarn versions in npm with npm view yarn versions --json (mostly 1.x versions are listed)

For me, what ended up working was deleting any existing yarn instances and then re-installing

# remove any instances of yarn so it doesn't conflict with corepack
rm -rf /opt/homebrew/bin/yarn # macos machines
rm -rf ~/.yarnrc.yml # linux machines

corepack enable
corepack prepare [email protected] --activate
YARN_ENABLE_IMMUTABLE_INSTALLS=false yarn install
