`ng generate @angular/material:navigation jnav` yields "... unhandled exception ..."

[JoeCodeswell]

What am I doing wrong? According to my interpretation of Navigation schematic the following ng generate ... command should have worked.

PS rbeNgMat>  ng generate @angular/material:navigation jnav
An unhandled exception occurred: Schematic "navigation" not found in collection "@angular/material".
See "C:\Users\joeco\AppData\Local\Temp\ng-KACyoy\angular-errors.log" for further details.
PS rbeNgMat>

Thanks in advance.
Love and peace,
Joe

This repository is for issues regarding Angular Material's documentation site. For general troubleshooting issues, I suggest you either submit a new issue on the angular/components repository or ask on StackOverflow.

Respectfully, Eric, I followed the documentation and it didn't work.

Can you please include the output of ng -v?

[Splaktar]

Please submit Angular Material and CDK questions here and issues here. This repo is for docs infrastructure only.

I've transferred this issue to the correct repository.

I looked into reproducing this, but wasn't able to. Based on the error being reported, it looks like an old version of the @angular/material is still installed. The schematic has been renamed to navigation from nav in v9. Can you please check if the latest version of Angular Material is used?

#18433 reported the same issue but the issue explicitly mentioned Angular Material version 8 being used. For versions below v9, the schematic is named nav.

Hi Folks. I was in the middle of documenting the steps i took to generate the app when the issue was transferred & i lost my edit. I still suspect this may be a documentation issue because

• v6 docs say
  ng generate @angular/material:material-nav --name <component-name>
• current docs say ng generate@angular/material:navigation <component-name>

I'll append my app creation log at the end.
RE "Can you please include the output of ng -v"
The creation log says:

PS system32> ng version

You can find the Angular Material version 8 docs here:

Hi @Splaktar and @devversion ,
Thanks for the help.
So I got 3 things from this.

1. The current docs are for Angular Material version 9
2. The correct command for Angular Material version 8, looking it up on https://v8.material.angular.io/guide/schematics, is
   ng generate @angular/material:nav <component-name>
3. The correct place for me to post this kind of issue is https://github.com/angular/components

I can report that this WORKED LIKE A CHAMP!
