title: Bower 0.8.5 seems to be stuck
body: <p>I updated from 0.8.0 (I guess) or later to 0.8.5 and bower seems stuck when i do a simple bower install. It happens on my machine and with my cloudbees hosted jenkins.
  I tried to do a <code>bower clean-cache</code>, a <code>bower install --force</code> and a <code>rm -rf ~/.bower</code> with no luck.</p>
  
  <p>It always gets stuck on copying instructions such as :</p>
  
  <pre><code>bower copying /home/bigx/.bower/cache/require/34f0965def4ee39276726c265c9162b6
  </code></pre>
  
  <p>or any other lib, there is no pattern.</p>
  
  <p>I've got the following when I try to reinstall bower (only on my machine not on cloudbees):</p>
  
  <pre><code>npm WARN unmet dependency /usr/lib/node_modules/modulus/node_modules/prompt/node_modules/winston requires pkginfo@'0.2.x' but will load
  npm WARN unmet dependency /usr/lib/node_modules/modulus/node_modules/prompt/node_modules/pkginfo,
  npm WARN unmet dependency which is version 0.3.0
  </code></pre>
  
  <p>And here is my component.json</p>
  
  <pre><code>{
      "dependencies": {
          "angular": "~1.0.5",
          "require": "~2.1.4",
          "jquery": "~1.9.1",
          "angular-sanitize": "~1.0.5",
          "foundation": "http://foundation.zurb.com/files/foundation-3.2.5.zip",
          "less.js": "~1.3.3",
          "font-awesome": "~3.0.2"
      },
      "devDependencies": {
          "angular-mocks": "~1.0.5"
      }
  }
  </code></pre>
  
  <p>Any idea?</p>
  
  <p>Regards,</p>
