Bug: eslint v9.0 peer dependency issues

[marijaduvnjak]

Environment

Node version: v20.12.2
npm version: v10.5.0
Local ESLint version: v8.57.0 (Currently used)
Global ESLint version: Not found
Operating System: linux 6.8.0-76060800daily20240311-generic

What parser are you using?

@typescript-eslint/parser

What did you do?

I tried to install the latest eslint v9.0.0 version in my nextjs project.

What did you expect to happen?

I expected that I could install the latest eslint without any issues.

What actually happened?

Instead, I ran into peer dependency issues during the installation:

This is because the version of the shareable configuration or plugin you are using does not currently support v9. You can try updating them to the latest version and keep an eye on v9 support for related dependencies
