Migrating to eslint 9.0.0 issue

I have next issue while upgrading eslint to 9.0.0

⋊> ~/A/fusion on turborepo ⨯ bun lint                                                          22:21:58

Oops! Something went wrong! :(

I don't use @humanwhocodes package, but it seems some other package uses it.

Solution

I think the issue might be that you include @typescript-eslint two times by using the spread operator with both compat.extends("standard-with-typescript") and tseslint.configs.recommendedTypeChecked.

If you check recommendedTypeChecked here: https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/src/configs/recommended-type-checked.ts

you can see it extends the base config: https://github.com/typescript-eslint/typescript-eslint/blob/main/packages/eslint-plugin/src/configs/base.ts

It includes the @typescript-eslint plugin.

I'm not sure what is happening with that FlatCompat thing you have going on there, but probably it results in including the same @typescript-eslint plugin again, leading to the error you get.
