Semantic ui installation hangs


I am trying install semantic ui via npm:

npm install semantic-ui --save

but it hands, I am stuck here:

What is it doing? Why there are some node.exe processes stuck doing nothing?
I also tried to install it from the master branch but I get stuck at the same point.


The be way to sort the issue is to install a previous version of semantic ui

npm install semantic-ui@2.2.1 --save-dev

once the install finishes run an update 

npm update
