title: Installing nose using pip, but bash doesn't recognize command on mac
body: <p>I'm trying to install nose on my computer for the Learn Python the Hard Way tutorial, but can't seem to get it to work.  I'm using pip to install:</p>
  
  <pre><code>$ pip install nose
  </code></pre>
  
  <p>And I get back: </p>
  
  <pre><code>Requirement already satisfied (use --upgrade to upgrade): nose in /usr/local/lib/python2.7/site-packages
  Cleaning up...
  </code></pre>
  
  <p>However, when I run the command nosetests, I get:</p>
  
  <pre><code>-bash: nosetests: command not found
  </code></pre>
  
  <p>I'm thinking there's something wrong with my PATH, but honestly I have no idea.  Any help would be greatly appreciated!</p>
