title: No distributions at all found for setup.py
body: <p>I'm having an issue with <code>pip install</code>. I am trying to download <code>SQLAlchemy</code> and download the gz file from <a href="https://pypi.python.org/pypi/SQLAlchemy/1.0.5" rel="nofollow noreferrer">here</a>. However, when I type <code>pip install setup.py</code> in the Command Prompt, I get:</p>
  
  <pre><code>Downloading/unpacking setup.py 
  Could not find any downloads that satisfy the requirement setup.py
  Cleaning up..
  No distributions at all found for setup.py
  </code></pre>
  
  <p>I've been facing a similar problem with <code>pip</code> when trying to download other libraries and this started occurring a day after I downloaded Python 3.4, when I was running Python 2.7 previously. I had a look at <a href="https://stackoverflow.com/questions/18230956/could-not-find-a-version-that-satisfies-the-requirement-pytz">this</a> and tried using <code>pip install --pre library_name</code>. However, this doesn't seem to working either and I get a similar message to the one above. </p>
  
  <p>Thank You</p>
