[M6stafa]

Version

3.0.0-beta.2

Reproduction link

https://github.com/M6stafa/test-new-vue-cli

Steps to reproduce

Open jest.config.js, it has some lint error.
If put .eslintignore in root and put this file in it, errors get disappear. (there is no .eslintignore at all)

What is expected?

no eslint error anywhere

What is actually happening?

eslint error in jest.config.js

---

When run npm run lint there is no linting error for this file 🤔 but in vscode you can see errors.
is there any reason that there isn't any .eslintignore at all?
