Schematic "library" not found in collection "@schematics/angular"

npm i -g @schematics/angular 

updates you to the latest version of the schematic. Also important to update your angular cli:

npm i -g @angular/cli

I got this error when I tried to generate a service myService:

ng generate myService

This fixed the problem:

ng generate service myService

Why can't someone make a UNIX shell that does what I want, not what I type? :-)
