Problem with NPM and Nova Card assets

Whenever I try to make a card, an obscure "events.js:291 throw er; // Unhandled 'error' event" shows - so the assets can't get compiled. What could the problem be here?

Would you like to compile the card's assets? (yes/no) [yes]:
 > yes

> dev
> npm run development


> development
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

events.js:291
      throw er; // Unhandled 'error' event
      ^
