Self-service

• I'd be willing to implement a fix

Describe the bug

Yarn pnp can't load synckit worker hence prettier plugin fails to run.
Why do I file this against yarn? Everything works as expected when installing the dependencies with npm.

To reproduce

Use NodeJS 20.9.0
Clone https://github.com/shermify/eslint-plugin-repro

> yarn install
> export NODE_PATH=".yarn/sdks"

Setting the NODE_PATH is equivalent to setting the VS Code eslint.nodePath setting.
start node REPL and execute the following commands (to ensure to mimic the executing since a VS Code extension):

require.resolve('eslint');

We will load the eslint npm module from .yarn/sdks

const library = require('eslint');

async function main() { const eslint = new (await library.loadESLint())(); const report = await eslint.lintText(`var test = "hello";`); console.log(report); }

main().then(() => { console.log('Promise resolved'); } ).catch((error) => { console.error(error); process.exitCode = 1; });

Observe: the promise never resolves.[+] You can't even terminate NodeJS using Ctrl+C. You have to kill it.[/+]
I debugged it in the context of the VS Code ESLint extension and the findings are here: microsoft/vscode-eslint#1856 (comment) and in the following comments.
