title: Django "./manage.py bower install" tells me bower isn't installed when it is
body: <p>I'm following the instructions from the django-bower setup readme <a href="https://github.com/nvbn/django-bower" rel="nofollow">here</a>. I've installed django-bower (v5.1.0) via <code>$ pip install -r requirements.txt</code> (django-bower==5.1.0 is in my requirements.txt). Now I'm trying to run <code>$ ./manage.py bower install</code> (as per the instructions) but I'm getting this error:</p>
  
  <blockquote>
    <p>BowerNotInstalled: Bower not installed, read instruction here - <a href="http://bower.io/" rel="nofollow">http://bower.io/</a></p>
  </blockquote>
  
  <p>Trying to run <code>$ pip install django-bower</code> gives me a <code>Requirement already satisfied</code> message. </p>
  
  <p>What am I missing?</p>
