Does Not Run with Bun

[Barzi-Ahmed]

Hi,

I use Bun for my project, and when I try to use "bun x eslint --inspect-config" or "bun x --bun eslint --inspect-config", it doesn't work and shows this error message:

$ eslint --inspect-config
You can also run this command directly using 'npx @eslint/config-inspector@latest' in the same directory as your configuration file.
'npx' is not recognized as an internal or external command,
operable program or batch file.

Please support Bun.

All the info you need is there in the message that’s printed?

As it say: eslint --inspect-config is simply a shortcut within eslint that runs npx @eslint/config-inspector

Since you’re on Bun the npx command fails. Do what the command recommends and do the Bun equivalent of npx @eslint/config-inspector directly instead of using the shortcut.

If you do want to file an issue about adding support for Bun in the shortcut, then you would have to file it towards the main ESLint project, not the config inspector.

@voxpelli ,

I did exactly that now, I get this error:

Bun v1.1.33 (Windows x64)

I get this error with all package managers in my project managed with bun, so not sure it's related.

This with npx:

Node.js v23.0.0

[antfu]

This looks like a bun bug to me. Bun should be responsible for bringing compatible with Node

[Razunter]

@antfu but it's not the Bun bug. I'm getting the same issue without Bun on Node v23. And it looks like it's the same without Node on Bun engine... And the same issue with Deno.

[voxpelli]

@Razunter @antfu Node 23, 22, 20 should all be tested in the CI but currently only latest LTS is. I suggest a PR to add the other versions to the text matrix
