title: Getting a permission error when installing with bower
body: <p>Everytime I try to install something with Bower I get a permission error like this:</p>
  
  <pre><code>Andreass-MacBook-Air:openMedia Andreas$ bower install jquery
  /usr/local/lib/node_modules/bower/node_modules/configstore/index.js:56
              throw err;
                    ^
  Error: EACCES, permission denied '/Users/Andreas/.config/configstore/bower-github.yml'
  You don't have access to this file.

  <p>I imagine there might be an easy solution to this. But this is my first experience with Bower. Thanks in advance.</p>
