title: beginner installing nosetests package
body: <p>I'm trying to install the following as per the learnpythonthehardway tutorial:</p>
  
  <ol>
  <li>pip from <a href="http://pypi.python.org/pypi/pip">http://pypi.python.org/pypi/pip</a> </li>
  <li>distribute from <a href="http://pypi.python.org/pypi/distribute">http://pypi.python.org/pypi/distribute</a> </li>
  <li>nose from <a href="http://pypi.python.org/pypi/nose/">http://pypi.python.org/pypi/nose/</a> </li>
  <li>virtualenv from <a href="http://pypi.python.org/pypi/virtualenv">http://pypi.python.org/pypi/virtualenv</a></li>
  </ol>
  
  <p>I've visited these links and clicked the download button; each file is in my downloads folder now, and I unarchive/unzipped them- not sure what this means but it seemed required. Are they "installed"? If not, what does it mean to really install them? I've tried typing <code>nosetests</code> in the terminal (as the book says you should), as well as tried <code>easy_install</code> but that doesn't seem to work. It appears my understanding is limited in a number of ways here. </p>
  
  <p>I get the following <code>-bash: nosetests: command not found</code>, but am trying to get:</p>
  
  <p><code>nosetests . ---------------------------------------------------------------------- Ran 1 test in 0.007s
  OK</code></p>
