title: Why won't npm package update to latest version?
body: <p>I have grunt-contrib-uglify installed at version 0.2.7. According to <a href="https://github.com/gruntjs/grunt-contrib-uglify" rel="nofollow noreferrer">the repo</a>, the latest version is 0.5. I tried to update via:</p>
  
  <pre><code>npm update grunt-contrib-uglify --save-dev
  </code></pre>
  
  <p>but this installs version 0.2.7 again. Am I supposed to manually update the version number in package.json and only then run the above line?</p>

  <p>Bonus question: Why didn't my npm update?</p>
