i try upgrade the version of AngularCli but the same error ng update @angular/cli --migrate-only --from=16.0 --to=<15.0> --allow-dirty --force
i delete the : node_modules\ @angular-builders\custom-webpack\node_modules
npm install -g @angular/cli@15
npm cache clear --force
It is erroring because you have Angular 16 installed but the CLI is version 15.x.
To upgrade Angular CLI, you can use the ng update command. For example, to update to the latest stable release of the core framework and CLI, you can run:
ng update @angular/cli @angular/coreYou do not have to use the latest version, but the CLI must be at or above the version of Angular you wish to use.
https://angular.io/cli/update
I would recommend (and I advise this for all Angular upgrades, especially if you use Angular material), that you use the exceptionally excellent interactive upgrade guide.
This link for example will show you all the steps for your version gap.
https://update.angular.io/?v=8.2-15.0
The command you show in your example is from 16 to 15 which would be a downgrade, the tool won't support migration in that direction. You can only go from a lower version to higher version.
