After updating to version 6 (before it works perfectly) i start to have this error: Error: Failed to load parser '@typescript-eslint/parser' declared in '.eslintrc.js': Cannot find module 'eslint/lib/util/traverser'

I’ve also tried to install package eslint-traverse but without success.

Any clues on this? Thanks! 😃
