node.js - node.jsにカルマをインストールできません

Question

ここに私が得るものがあります：

H:\>npm install -g karma npm http GET https://registry.npmjs.org/karma npm http GET https://registry.npmjs.org/karma npm http GET https://registry.npmjs.org/karma 
npm ERR! Error: connect ETIMEDOUT npm ERR!

私はnode.jsの初心者です。angularjsアプリケーションの単体テストにカルマを使用したいので、私はそれを使用しています。

何が起こっているのですか？
