Failed at the ionic@2.0.0-beta.18

Hey Ionites… someone can help me?
Work with Ionic2 on Mac last week and everything was perfect.
Now I tried update to ionic@2.0.0-beta.18 and got the error:

npm ERR! Darwin 15.2.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "i" "-g" "cordova" "ionic@beta"

npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the ionic package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR!     node lib/tasks/postinstall
npm ERR! You can get information on how to open an issue for this project with:
npm ERR!     npm bugs ionic
npm ERR! Or if that isn't available, you can get their info via:
npm ERR!     npm owner ls ionic
npm ERR! There is likely additional logging output above.

npm ERR! Please include the following file with any support request:

Node and NPM are updated with:

node -v 
npm -v

Any help?
