Estoy tratando de seguir estotutorial para crear un proyecto ficticio usando gem react_on_rails

Supongo que he seguido cada paso del tutorial, pero en el último paso donde tenemos que ejecutar el proyecto aparece un error relacionado con el nodo js. Incluso actualicé la versión de mi nodo en el sistema, todavía enfrento el mismo problema

Error
