Running 'ng generate page song' results in 'Invalid Blueprint' error

[JoshuaPK]

When I type 'ng generate page song', I get the error, "Invalid Blueprint: page". My Ionic setup is as follows:

onic:

Ionic CLI : 5.4.16 (/home/josh/dev/node_modules/lib/node_modules/ionic)
Ionic Framework : @ionic/angular 4.11.10
@angular-devkit/build-angular : 0.801.3
@angular-devkit/schematics : 8.1.3
@angular/cli : 8.1.3
@ionic/angular-toolkit : 2.1.2

Utility:

cordova-res : not installed
native-run : not installed

System:

NodeJS : v10.16.3 (/usr/bin/node)
npm : 6.9.0
OS : Linux 4.18

This works if I instead do 'ionic generate page song', as it then runs ng and generates the page.
