What’s your quasar.conf? Seems like you are instantiating the linter in a wrong way.

[rstoenescu]

I remember that at some point in time the official starter kit had a "CLIEngine" reference for the linter in quasar.conf.js.
But if you updated the linter (which is most likely), then you also need to update the linter config yourself (or create a new Quasar app and copy the linting from there).

Please feel free to reopen if I missed anything.

[afnan]

hen you also need to update the linter config yourself

Thank you for your detailed reply. My quasar conf file is as follow. I have tried installing the new quasar app and compared the conf file. They are the same. Also, I get with new install.

You use eslint 8, fork-ts-checker (used behind the curtains to manage TS checking) isn't compatible with that yet: TypeStrong/fork-ts-checker-webpack-plugin#664

You use eslint 8, fork-ts-checker (used behind the curtains to manage TS checking) isn't compatible with that yet: TypeStrong/fork-ts-checker-webpack-plugin#664

Since it does not affect the working, its just wait and see till it becomes compatible?

[IlCallo]

Possibly? Even if I won't bet on that, fork-ts-checker will remove ESLint support into the next major release so he possibly isn't willing to support ESLint 8 at all, but the maintainer is the one you should really ask to
