Vous avez des dépendances incompatiibles, j'ai résolu ce problème en modifiant le package.json d'un autre projet angulaire puis après le changement de ce packag.json, vous ne modifiez que les versions de dépendances que vous avez.
après le changement, écrivez:
-npm lien
-npm servir -o
alors c'est du travail :)
