title: How to use a specific version of NPM?
body: <p>How can I switch which version of npm I'm using?</p>
  
  <p>Currently:</p>
  
  <pre><code>$ npm -v
  1.1.65
  </code></pre>
  
  <p>But I need: 1.0.x</p>
  
  <p>I tried but got an error:</p>
  
  <pre><code>$npm version 1.0
  npm ERR! version No package.json found
  </code></pre>
  
  <p>Anyone know how to use a different version of NPM? Thanks</p>
