Dealing with multiple Python versions?
<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>

<p>Take a look at pyenv located in <a href="https://github.com/yyuu/pyenv/blob/master/README.md" rel="nofollow">https://github.com/yyuu/pyenv/blob/master/README.md</a>. </p>

<p>You can install multiple versions of python and pip. </p>

<p>The README has instructions for installing pyenv,  installing wanted python versions and switching between them. </p>

python python-2.7 pip conda pydatalog
