title: Dealing with multiple Python versions?
body: <p>I have a problem with my Pip version. I am trying out to install the pyDatalog package, which isn't supported by Anaconda.</p>
  
  <pre><code>   The following specifications were found to be in conflict:
    - pydatalog
    - python 3.5*
  </code></pre>
  
  <p>In my Ubuntu, I have two versions of Python (2.7 and Anaconda with 3.5). For Python 2.7 I don't even know whether or not Pip is installed.</p>
  
  <p>How can I have two different versions of Pip for different versions of Python on one computer? Can I use one version of Pip for both version of Python?</p>
