Can't update ionic lib

Trying to run ionic lib update or ionic lib update -v 1.2.1 but just get this…

bower ionic#1.1.0               cached git://github.com/driftyco/ionic-bower.git#1.1.0
bower ionic#1.1.0             validate 1.1.0 against git://github.com/driftyco/ionic-bower.git#1.1.0

How can I update my ionic project to the latest version?

Thanks

Try removing ‘-v’ option

Yeah I did try that without specifying a version, it just did that same thing and stayed on 1.1.0

try clearing bower components bower cache clean and then try to update by ionic lib update
