eslint-config-preact': Cannot find module 'eslint-plugin-jest'

[bendgk]

I created a new preact project using the cli npx preact-cli create typescript my-project
I tried to enable ESLint in my IDE (Webstorm) and receive the following error upon lint

Error Log:

Sorry for the late response, hopefully you found a fix but you'd probably just need to do a clean install. eslint-plugin-jest is most certainly labeled as a dependency and should get dragged in on install of this config.

"eslint-plugin-jest": "^23.7.0",

Looks like this is a longstanding bug in eslint itself eslint/eslint#3458

[jakejarvis]

Assuming this is related? Getting this error after bumping to 1.3.0, looks like this possibly broke with jest-community/eslint-plugin-jest#970 but I haven't investigated too deeply. Adding jest itself as a devDependency silences it for now if anybody needs a quick fix, even though I don't use it. :)

$ run-s lint:**
$ eslint .

Oops! Something went wrong! :(

ESLint: 8.4.1

Same for me, after bumping to 1.3.0.
I don't use jest and prefer not to install it.

Other workaround is to add jest version to .eslintrc.json:

{
  "root": true,
  "extends": [
    "preact"
  ],
  "settings": {
    "jest": { "version": 27 }
  }
}

[dolie]

Same as @piotr-cz . Thank you for the workaround.
I'm using another test runner. I hope to see a proper fix soon.

Other workaround is to disable this rule by adding:

    "rules": { "jest/no-deprecated-functions": 0 }

I have some similar issues, but using eslint_d.

Everything seems fine with eslint, but for something breaks with eslint_d:

Error: Failed to load plugin 'jest' declared in '.eslintrc.json » eslint-config-preact': Cannot find module 'eslint'

I feel like this is somehow related.
