Looks like the issue is in 0.7.0 of the Angular devkit.

[mruknowme]

So there is no problem in earlier versions? (This one ships with Angular CLI 6.1.0)

[joshuamorony]

I'm getting the same issue - seems to be with all generate commands except page. Both ionic g page and ng generate page will work, but service, component, directive, pipe won't.

[imhoffd]

Please apply these version changes to your projects or start a new project once the starters are finished deploying ~10min (wait for green check mark on latest commit: https://github.com/ionic-team/starters/commits/master)

I created an issue to attempt to avoid issues like this in the future: https://github.com/ionic-team/starters/issues/358

Thanks, and apologies for that.

[mruknowme]

Ok, no problem, will try soo and let you know if I face further issues. Thank you!

[joshuamorony]

Can confirm it works now - thanks!

[imhoffd]

I think I can close this, right?
