Impossible de mettre à jour angular vers la version 6

J'essaie de mettre à jour angular à la dernière version.

J'ai mis à jour global @ angular/cli

npm install -g @angular/cli

Ensuite, lorsque j'essaie de mettre à jour local @ angular/cli en utilisant ng update @angular/cli, j'obtiens cette erreur: 

Error: Unexpected end of JSON input

Voici mon package.json

Le format est correct.

le projet est en cours de compilation et fonctionne au moment de servir.

J'utilise v9.9.0 du noeud et 6.0.1 du npm.

Juste pour être sûr de suivre les étapes suivantes:

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@latest

Puis dans votre package de projet Local:

rm -rf node_modules dist 
npm install --save-dev @angular/cli@latest
npm i 
ng update @angular/cli 
ng update @angular/core

Si cela ne fonctionne pas, je pense que vous devriez mettre à jour manuellement le package.json

Le problème était d'avoir ng installé sous/usr/local (et un lien symbolique dans/usr/local/bin). Le supprimer m'a aidé à mettre à jour ma version de @ angular/cli vers la version 6 (à partir de la version 1.7.1).
