What version of Bun is running?

1.0.1+31aec4ebe325982fc0ef27498984b0ad9969162b

What platform is your computer?

Linux 5.10.16.3-microsoft-standard-WSL2 x86_64 x86_64, Linux 5.19.0-45-generic x86_64 x86_64

What steps can reproduce the bug?

I have two machines:

• one with Windows 10, running Linux 5.10.16.3-microsoft-standard-WSL2 x86_64 x86_64 (Ubuntu 22.04.2 under WSL)
• second with Linux 5.19.0-45-generic x86_64 x86_64 (Ubuntu 22.04.2)

I have the same package.json on both machines:

{
  "name": "bun_puppeteer_tests",
  "module": "index.ts",
  "dependencies": {
    "puppeteer-core": "^21.2.1"
  },
  "devDependencies": {
    "bun-types": "^1.0.1"
  },
  "scripts": {
    "start": "bun run index.ts"
  },
  "type": "module"
}

And the same index.ts contents:

import puppeteer from "puppeteer-core";

await puppeteer.launch({
  headless: false,
  args: ["--no-sandbox", "--disable-dev-shm-usage", "--disable-setuid-sandbox"], // Optional, was trying these
  ignoreDefaultArgs: ["--disable-extensions"], // Optional
  executablePath: "/usr/bin/chromium-browser", // Or any standalone version from https://googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.json
});

process.exit();

Then do bun run start

What is the expected behavior?

On a Linux 5.19.0-45-generic x86_64 x86_64 machine it works as intended: I see an expected behavior, where browser window opens up.

On a Linux 5.10.16.3-microsoft-standard-WSL2 x86_64 x86_64 I see an errors in output:

What do you see instead?

Additional information

I kinda can't wrap my head around regarding how it should work under WSL... Is it intended to work at all? I've also tried to call an .exe version of Chrome standalone, but of course the error was TypeError: Executable not found in $PATH, because I was tying to run a Win excutable while being in Ubuntu's WSL mode.

Does it mean that you by default can not run things like Puppeteer under WSL? Thanks for an answer, will wait for knowledge :)
