Unable to recreate a yarn.lock

[davidbrochart]

Description

I thought it would be possible to recreate a yarn.lock, by removing it and invoking jlpm, but I get this error at jlpm run build:

> @jupyterlab/buildutils@4.1.2 build
> tsc && cd template && npm run build

../node_modules/@yarnpkg/fslib/lib/ZipFS.d.ts:208:5 - error TS2416: Property 'readdirPromise' in type 'ZipFS' is not assignable to the same property in base type 'BasePortableFakeFS'.

Reproduce

1. git clone https://github.com/jupyterlab/jupyterlab.git
2. cd jupyterlab
3. pixi init
4. pixi add pip nodejs
5. pixi shell
6. pip install hatch
7. pip install -e .
8. rm yarn.lock
9. jlpm
10. jlpm run build

This issue suggests that this issue has been fixed in later version of yarn, but it seems that JupyterLab vendors yarn v3.5.0.

Expected behavior

We should be able to recreate a yarn.lock.

Context

• Operating System and version: Linux Ubuntu 22.04
• Browser and version: N/A
• JupyterLab version: main branch

I think this can be closed since #15996 bumped the yarn version used in buildutils to fix this issue, see comments #15996 (comment) and #15996 (comment).
