npm install ws não funciona

Question

Eu quero implementar um servidor websocket em node.js. Para isso quero instalar o 'ws'. Eu já instalei o npm e node.js no meu sistema Ubuntu. Agora estou tentando executar o comando 'sudo npm install ws' mas não funciona. Estou colando o conteúdo do meu terminal. Alguém pode ajudar?

root@Neeraj:/home/neeraj# npm install ws
npm http GET https://registry.npmjs.org/ws

Esta postagem resolveu meu problema , tão fácil quanto estabelecer o registro npm com

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

De qualquer forma, obrigado!
