Docs lack how to uninstall Yarn 2

[desmap]

There are no docs and it's discouraged to rm .yarn in #1733 so what should we do?

This is crucial since Yarn 2 creates anomalies with other stuff, eg CRA but this should not be the focus here. I need to get Yarn 2 from my system or I must re-setup my machine :/

Edit: I changed the title bc the main issue is that there are no docs to get rid of berry; after 30 min of googling, reading tons of SO replies you know how to get there but man, this is not a nice UX and leaves users grumpy. You, we, nobody has time. FWIW and again, Yarn 2 totally messes up CRA if anyone cares.

The doc clearly states that the install is project-local. If you derive from it that you need to reinstall your machine to switch back to something else, you missed something.

Yarn 2 doesn't mess up CRA, PnP highlights the issue in CRA which just happens to work under the old node_modules layout which is suggested to enable in the migration guide for the initial migration, which I'm assuming you skipped https://yarnpkg.com/getting-started/migration

The fix for CRA has been sitting there for months, if you want to complain, this is the wrong place facebook/create-react-app#9872

But how do you uninstall Yarn?

[hades200082]

Yarn v2+ has caused me so many issues. I just want it gone off of my machine.

I've tried corepack disable I've tried npm install -g yarn to go back to v1 but nothing works. Please explain how to get rid of Yarn v2+ and revert to classic Yarn until yarn v2+ & pnpm can just work without issue on projects.

I have same problem, And after the upgrade, the package installed globally in yarn v1 cannot be uninstalled normally. yarn global Command deleted 🤯🤯🤯

Using yarn set version classic worked for me when I needed to revert it for a project

That worked for me. Thanks 👍

to anyone having issues with this on Windows, make sure you also delete your "yarnrc.yml" both in local project and your user folder, as that will also affect which version the system thinks it needs to use.

None of the 'standard' ways of uninstalling worked for me on windows 10.

In the end I delete all files yarn* from:

c:\Users<USER>\AppData\Roaming\npm

This worked straight away. Im not sure how safe this approach is.

Came here after looking everywhere about how to uninstall Yarn. Would love better documentation on this. Thanks.

I tried using yarn set version classic but it created config files in my project that I wasn't happy with (not allowed to commit non-task related changes). Had to revert.

A Stack Overflow thread helped me with what looks to be a global downgrade method:
corepack prepare [email protected] --activate

Not sure if this method is correct but it worked for me.

So you can't remove yarn? any of the replace options do not work for me.

[Dan503]

I needed to run these commands:

npm uninstall corepack -g
npm i yarn -g

I also had to downgrade node to v18.19.1

I am also suffering from this issue.

corepack is a disaster, had to follow Dan503's advice

I have no idea why developers keep messing up so much with breaking changes with libraries and creating such an amount of issues.
This is bad from yarn to the point that I'll probably abandon as many already did.

This unfriendly first answer to something so essential is the proof.

So using NVM I'd to do pretty much all the types of uninstall possible.
Using the current node version, corepack still has to be enabled:

• Set the current yarn version with corepack prepare [email protected] --activate
• Remove node version of NVM to remove everything, then add it again

In your project, if you still have issues when you run yarn like

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

you need to add the configuration to your package manager, e.g.:

"packageManager": "[email protected]"

Then run the command yarn set version classic.

Note: That also means that you may have been trying to install globally yarn on your root, which creates a package.json with the mentioned version, "packageManager": "[email protected]" in my case. This also needs to be removed.

Finally you can go back to work 😓
