I would like to upgrade my project to angular 6.
So, I upgrade npm, then install @angular/cli@latest globally and locally.
Ok, to complete the process I have to create a new file named (angular.json) wich replace angular-cli.json:
ng update @angular/cli
But here I have an error:
Registry returned 404 for GET on https://registry.npmjs.org/daypilot-pro-angular
For information, I have the same issue with the sample project "angular6-scheduler"
