Sudo npm install -g cordova ionic doesn`t work on my mac

I installed node & npm package from (node v.4.4.0, npm v.2.14.20, also tried latest npm version).
After that I tried to install ionic: sudo npm install -g cordova ionic, but it failed with output:

Any ideas how to fix this trouble?
Thanks in advance!

I recently updated my whole brew system, updated node, and updated npm.

I had the same problem. using the:

‘sudo npm install -g cordova ionic’

I was able to install cordova with ‘sudo npm install -g cordova’

then install ionic with ‘sudo npm install -g ionic’

hope that helps
