When trying to use the V4 CLI to run a project with Cordova using ionic cordova run browser -lcs, I get the error

Thanks @cwoolum, looks like this is leftover from the Angular CLI 1 -> 6 beta upgrade.

[cwoolum]

This may be an issue with the Angular CLI. I have added a bug there to get more information angular/angular-cli#10455

I think it's just an option that was removed. The output path (www/, for us) is no longer removed, so the option is meaningless.

[cwoolum]

Aaah, okay. Thanks!
