Were you now able to reproduce? and if so, is there still an intention to fix the issue in Yarn Classic?

@MikeMcC399 yeah, I was able to reproduce, I have no idea why it's doing that. I'll try to look into it further.

@JJJ

Also still seeing this.

That is to be expected, since this issue is still open. It was however great to read #9013 (comment) which said:

Update: I spoke with the team, it looks like the cause was already identified and fixed, but has not been released yet.

so that leads me to believe that if we wait, then the fix will be released in a new patch of Yarn > v1.22.21.

Here's my deprecation output:

This is basically the same stack trace as I posted in #9013 (comment).

You then have warnings concerning @ava/babel which you would need to research in their repo. The same for the other similar warnings.

error @ava/typescript@4.1.0: The engine "node" is incompatible with this module. Expected version "^14.19 || ^16.15 || ^18 || ^20". Got "21.6.0"
error Found incompatible module.

This error from @ava/typescript says that it is not compatible with Node.js 21. It may prevent your migration to Node.js 21, however this is not a problem that Yarn can help you with.

MikeMcC399 · 2024-01-22T07:55:53Z

@basiq-ash

Facing same issue, is there any update on this?

The last update is from last week. See #9013 (comment)

MikeMcC399 · 2024-01-23T09:17:33Z

The issue is also reproducible if Yarn Classic is used to set the version to Yarn Modern:

nvm use 21
corepack disable
npm install yarn -g
yarn set version stable

If you want to register that you are also interested in a resolution for this issue, I suggest you "up-vote" it by clicking on the 👍🏻 icon in the original post #9013 (comment) instead of adding a separate new comment:

MikeMcC399 · 2024-02-18T09:56:14Z

@RDIL

You wrote in #9013 (comment) back in January that the issue was fixed and not yet released. Can you share any planning date for a potential release?

RDIL · 2024-02-20T16:18:40Z

I don't honestly know. It's not up to me, and Yarn Classic is deprecated in favor of Berry, and is currently only getting high priority updates. I understand that it's not possible in all cases but I highly recommend migrating if you are able.

I'll try to bump this again but I can't guarantee anything.

MikeMcC399 · 2024-02-20T16:44:39Z

@RDIL

Many thanks for your attention to this! I do appreciate that Yarn Classic is deprecated and in terms of using Yarn Classic as a standalone item I would understand if this issue were designated as "won't fix".

I would be more concerned about the use of Yarn Classic in order to set up Yarn Berry (Modern) which provokes the punycode warning. Perhaps this is then more of an issue which needs to be transferred to Yarn Berry?

https://yarnpkg.com/getting-started/install says

The preferred way to manage Yarn is by-project and through Corepack, a tool shipped by default with Node.js. Modern releases of Yarn aren't meant to be installed globally, or from npm.

This is however slightly problematic as Node.js Corepack documentation classifies Corepack with Stability: 1 Experimental and the Node.js documentation says "Use of the feature is not recommended in production environments."

So the choice is between the devil and the deep-blue sea in Node.js 21 environments:

without Corepack means relying on the deprecated Yarn Classic to install Yarn Modern and that provokes the punycode deprecation warning
with Corepack Yarn Modern can be installed without any punycode deprecation warning, but at the cost of using the Corepack function which is not recommended for production use

MikeMcC399 · 2024-04-11T19:24:49Z

@bennettfrazier

The most likely reason that you are still getting a punycode deprecation message is that it is coming from a package which is not Yarn. Have you set the environment variable
export NODE_OPTIONS='--trace-deprecation' (or similar depending on your operating system and terminal type)
and run your command to get trace information?

aryankarim · 2024-04-15T23:07:36Z

@MikeMcC399

I use node: v21.6.2 and yarn: 1.22.22.

Then I ran building NextJS v.14.2.1 with yarn build with --trace-deprecation

You're right. I've checked node-fetch's github, they're working on it.

But I still got the warning even with yarn info yarn description

However, this upgrade fixed it.

$ npm install yarn@latest -g

Going to be locking this issue because of the influx of comments that are not caused by Yarn. If anyone is able to reproduce this bug as a direct result of Yarn (using --trace-deprecation) on the new fixed version, please open a new issue. Thanks.
