无法运行ng generate @ angular / material：material-nav

Question

I am trying to setup Angular Material on an Angular 6 project. However, When attempting to run:

ng generate @angular/material:material-nav --project=ui-project

I get the following error message:

Cannot read property 'replace' of undefined

Answer 1

After a few weeks, and redoing the entire angular project object, I ended up having to upgrade the cli to version 7. Using the ng update -all command updated all the dependancies to the correct version and this worked fine.

Here is the result
