title: Error running nosetests
body: <p>I recently reinstalled <code>nose</code> to run tests on my code. </p>
  
  <p><a href="https://nose.readthedocs.org/en/latest/" rel="noreferrer">https://nose.readthedocs.org/en/latest/</a></p>
  
  <p>I used </p>
  
  <pre><code>sudo pip install nose
  </code></pre>
  
  <p>and went to my project folder. The response is </p>
  
  <pre><code>-bash: nosetests: command not found.
  </code></pre>
  
  <p>So, I once again I uninstalled and tried installing <code>nose</code> with MacPorts:</p>
  
  <pre><code>sudo port install py27-nose
  </code></pre>
  
  <p>In my project folder, I run </p>
  
  <pre><code>nosetests-2.7 filename.py
  </code></pre>
  
  <p>and I get the following error: </p>
  
  <pre><code>ERROR: Failure: ImportError (No module named nose_parameterized)
  </code></pre>
  
  <p>What's the problem? </p>
  
  <p>EDIT: More information. <code>nose</code> is installed. I get <code>Successfully installed nose-1.3.6</code>. </p>
