I just had the same problem.
It’s related to release v6.0.0-rc.2, https://github.com/angular/angular-cli/releases:
New configuration format. The new file can be found at angular.json (but .angular.json is also accepted). Running ng update on a CLI 1.7 project will move you to the new configuration.
I needed to execute:
ng update @angular/cli --migrate-only --from=1.7.4
This removed .angular-cli.json
and created angular.json
.
If this leads to your project using 1.7.4, install v6 locally:
npm install --save-dev @angular/[email protected]
And try once again to update your project with:
ng update @angular/cli --migrate-only --from=1.7.4
