Why doesn't npm install anything globally?

Question

ubuntu

Hello, please tell me what could be the problem, I installed nodejs from the ppa repository. Why can't I install bower globally? I write
npm install -g bower
or
sudo npm install -g bower
The result is the same, nothing happens, just waiting ..... I waited 20 minutes, nothing happened, what could be the problem? I have Ubuntu 14.04, it doesn't cost anything other than npm nodejs and git.
This has never happened before... Please help me figure it out...
