title: Nodejs - npm install permanently freezes
body: <h1>I am having weird issues with npm: the installation process permanently freezes on the load stage.</h1>
  <p>After nodejs installation, I tried to install angular-cli , but it stuck on the load stage:</p>
  <pre><code>c:\&gt;npm install -g @angular/cli
  npm info it worked if it ends with ok
  npm info using npm@3.10.10
  npm info using node@v6.11.3
  npm info ok
  npm info it worked if it ends with ok
  npm info using npm@3.10.10
  npm info using node@v6.11.3
  npm info attempt registry request try #1 at 1:35:34 PM
  npm http request GET https://registry.npmjs.org/@angular%2fcli
  npm http 304 https://registry.npmjs.org/@angular%2fcli
  npm info addNameTag [ '@angular/cli', 'latest' ]
  [|||||..............] - loadRequestedDeps: info addNameTag [ '@angular/cli', 'latest' ]
  </code></pre>
  <p>Same thing happens with other packages installation, for example Yarn:</p>
  <pre><code>c:\&gt;npm install -g yarn
  npm info it worked if it ends with ok
  npm info using npm@3.10.10
  npm info using node@v6.11.3
  npm info ok
  npm info it worked if it ends with ok
  npm info using npm@3.10.10
  npm info using node@v6.11.3
  npm info attempt registry request try #1 at 1:38:08 PM
  npm http request GET https://registry.npmjs.org/yarn
  npm http 304 https://registry.npmjs.org/yarn
  npm info addNameTag [ 'yarn', 'latest' ]
  [|||||..............] \ loadRequestedDeps: info addNameTag [ 'yarn', 'latest' ]
  </code></pre>
  <p>Please help, what could be a possible reason for that and how to fix it ?</p>
