Upgrade ionic2 beta.2 - got error

[mhartington]

Please checkout some of the recent changes. We’ve changed the build structure recently and that comes with a new ionic CLI, so make sure you upgrade the CLI as well.

npm install -g ionic@beta

ATTENTION: Upcoming Ionic 2 Starter Changes

Hello Ionites! Just want to give the community a heads up about changes that are going to be happening to Ionic 2 projects. None of these have happened yet, but we want to give everyone a word of warning before everything breaks and the world ends. This has been done The first one will be moving from the ionic-framework package name to ionic-angular. We will still publish ionic-framework for the next release, but the starters will move to ionic-angular once the CLI has been updated…
