title: Install Python 3.5.2, but pip for Python 2.6
body: <p>VPS-server was a version Python 2.6, I installed version Python 3.5.2.
  When I try to install some packages with help <code>pip</code>, I got errors.</p>
  
  <p>During installation packages:</p>
  
  <pre><code>DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6
  </code></pre>
  
  <p>Versions:</p>
  
  <pre><code># Python -V
  # Python 3.5.2
  
  # pip -V
  # pip 8.1.2 from /usr/lib/python2.6/site-packages/pip-8.1.2-py2.6.egg (python 2.6)
  
  # cat /etc/*-release
  # CentOS release 6.8 (Final)
  </code></pre>
