I can duplicated based on this project https://github.com/justinlevi/Decoupled-Drupal-8-Starter-Kit/tree/master/front-end

@justinlevi this is a problem in the ESLint npm library itself. TO verify can you run ESLint from the terminal and see if you get the same exception. If yes, please report the issue here: https://github.com/eslint/eslint

The issue seems intermittent and is no working. I'll report back here if it pops up again.
