Npm hangs when install @ionic/cli-plugin-cordova

Hi all,

thought nobody face these kind problem

update to Ionic CLI v3, npm will hang when installing @ionic/cli-plugin-cordova

but @ionic/cli-build-ionic-angular install correctly, I’m not sure if is npm’s problem.

I already upgrade npm to latest.
