Cannot install Ionic through npm

Question

I have been now trying to install Ionic framework through npm but with no success. I am trying the usual command,

npm install -g ionic

I already have cordova installed. I have updated my npm version to be the latest and also tried,

npm cache clean

npm config set registry https://registry.npmjs.org/

But I am still getting the following errors:

Any thoughts? Thanks
