Can't reproduce.. can't recognize your error either. Looks like you've screwed up your composer.json file.

Het is niet de bedoeling dat je de file kopieert van Github. Je kunt in een lege map simpelweg composer require pendonl/php-club-dataservice doen, composer maakt vervolgens de nodige files en directories aan.

Even bij het begin beginnen: https://getcomposer.org/doc/01-basic-usage.md
