Any codes.

I updated this library to v17.0.1 and still get these lint errors. Any way to fix them?

@nikitavoloboev it sounds like ESLint is picking up a different version of the parser from node_modules. Paste your ESLint config and [dev]Dependencies.

@sandrocsimas I should've asked for the exact error message and your lockfile in a gist. I don't see any dependencies (typically eslint-{config,plugin}.*) that export this project. See https://github.com/eslint/typescript-eslint-parser#usage-with-eslint.

FWIW, moving to "typescript-eslint-parser": "^17.0.1" and "eslint": "^5.2.0" fixed this for me

eslint / typescript-eslint-parser
