Repro steps
- use a project on @angular/cli 1.7.4 with a custom
.npmrccontaining credentials for connecting to custom npm registry - follow update steps described at https://update.angular.io/
Observed behavior
running the step ng update @angular/cli results in an error message 401 unauthorized.
Removing the custom .npmrc along with internal dependencies from package.json and running ng update @angular/cli succeeds
Desired behavior
ng update @angular/cli works without removing the custom .npmrc or at least prints a more useful error message
