Ah, that would be because you're using eslint globally, correct?

[David-Else]

@bradzacher No, it is not installed globally, it is in the local project directory. If i type eslint on the command line I get bash: eslint: command not found...

I am using pnpm and it is giving me some funny errors in relation to global installs, could it be that, or should your fix sort things out?

Thanks for the quick response!

[bradzacher]

It's probably pnpm. I forgot to add a dependency with a new experimental rule.
It should just work for everyone because it's also dependency for eslint itself, but things like yarn pnp will fail because it wasn't declared. I assume pnpm would fail in teh same way.

Try the canary tag on npm and it should work fine now!

[David-Else]

I just installed 1.8.1-alpha.2 and it works again, cheers!
