When Upgrading from angular 8.2 to angular 9 I got this error
An unhandled exception occurred: Cannot find module '@angular-devkit/schematics'
How can I overcome this error?
this is the used command:
ng update @angular/core @angular/cli --next
I can overcome this issue when running this command before the update command
npm i --save-dev @angular-devkit/schematics
