Erreur lors du lancement du serveur avec npm run serve - VueJS

Bonjour,

Je n'arrive pas à lancer mon serveur de developpement avec npm.

Ce que je fais

Au depart le projet fonctionnait bien. puis un jour j'ai rencontré cette erreur:

23 error If you do, this is most likely a problem with the vue-light-bootstrap-dashboard package,
23 error not with npm itself.
23 error Tell the author that this fails on your system:
23 error     vue-cli-service serve --open
23 error You can get information on how to open an issue for this project with:
23 error     npm bugs vue-light-bootstrap-dashboard
23 error Or if that isn't available, you can get their info via:
23 error     npm owner ls vue-light-bootstrap-dashboard
23 error There is likely additional logging output above.
24 verbose exit [ 1, true ]

J'ai alors redemarrer mon ordinateur et tout fonctionnait bien a nouveau. Puis la meme erreur survient, je redemarre alors tout va bien une fois de plus. Et maintenant que l'erreur survient, je redemarre rien ne se passe

Je ne sais vraiment pas d'où me vient cette erreur
