le service échoue avec le fichier d'espace de travail local ('angular.json') introuvable angulaire 5

d'abord je suis dans le bon répertoire

J'ai essayé de servir qui a fonctionné plus tôt aujourd'hui, mais maintenant je reçois les erreurs suivantes: 

Local workspace file ('angular.json') could not be found.
Error: Local workspace file ('angular.json') could not be found.

alors j'ai couru ng update @angluar/cli --migrate-only --from 1.7.4

Je l'ai fait en suivant la première réponse de ce message de débordement de pile: Erreur: le fichier d'espace de travail local ('angular.json') était introuvable

l'erreur de la mise à jour:

ce qui est werid est je n'ai aucune idée comment résoudre ce problème. 

mettre à jour: 

J'ai supprimé package-lock.json puis exécuté npm install puis essayé de servir, puis j'ai reçu la même erreur qu'avant le fait que ma configuration avait changé et que je devais exécuter ng update. 

exécuter la mise à jour et obtenir la même erreur que ci-dessus.

tenté cette correction: 

npm install --save-dev @angular/[email protected]
ng update @angular/cli --migrate-only --from=1.7.4

alors eu cette erreur:

J'ai eu le même problème Souhaitez-vous essayer comme suit: 

npm install -g angular-universal-pwa@beta
ng new --collection angular-universal-pwa myAwesomeApp
cd myAwesomeApp

Quand le demandeur dit

d'abord je suis dans le bon répertoire

... c'était mon problème.

Vous devriez exécuter ng test dans votre répertoire angulaire.
Si votre projet comporte plusieurs répertoires, assurez-vous de sélectionner le répertoire approprié avant d'exécuter les tests.
