Ok that's weird, i had alpha31 when updated, i did it with this command:
$ npm uninstall -g ionic && npm uninstall -g cordova && npm cache clear && npm cache clean && npm i -g cordova && npm i -g ionic@beta
Since the beta cli is out i would suggest that you update like this as it will wipe out global install and cache and reinstall from zero, be aware it will take between 10 min and 1 hour accordingly to your pc performance.
Now i haven't tried with npm i ionic-framework and can't test until monday but maybe a clean install and installing locally ionic-framework could fix something, we lose nothing with trying.
