Reproduce

$ yarn add eslint typescript @typescript-eslint/eslint-plugin @typescript-eslint/parser
$ npx eslint .
Failed to load parser '@typescript-eslint/parser' declared in '.eslintrc » plugin:@typescript-eslint/recommended » ./configs/base.json': Cannot find module 'eslint/lib/util/traverser'

Eslint 6 is released today. Both the parser and the plugin does not work in eslint 6. Failure in parser also fails the test of other eslint plugins.
