title: Ubuntu: pip not working with python3.4
body: <p>Trying to get pip working on my Ubuntu pc. pip seems to be working for python2.7, but not for others.</p>
  
  <p>Here's the problem:</p>
  
  <pre><code>$ pip
  Traceback (most recent call last):

  ImportError: No module named 'pip'
  
  $ which pip
  /usr/local/bin/pip
  
  $ python2.7 -m pip //here can be just python, btw
  Usage:   
  /usr/bin/python2.7 -m pip &lt;command&gt; [options]
  //and so on...
  
  $ python3.4 -m pip
  /usr/bin/python3.4: No module named pip

  <p>There's no /usr/bin/pip btw.</p>
  
  <p>How can I fix this issue to work with pip and python 3.4 normally?
  I am trying to use pycharm, but it's package manager also stucks in this problem.</p>
  
  <p>Thanks for attention!</p>
