title: pip3 on ubuntu 12.04 - syntax error
body: <p>I have installed pip3 on Ubuntu 12.04 by typing the following:</p>
  
  <pre><code>sudo apt-get install python3-setuptools
  
  sudo easy_install3 pip
  </code></pre>
  
  <p>As result, I get: </p>
  
  <pre><code>Searching for pip

  <p>But when I type:</p>
  
  <pre><code>pip3 --version
  </code></pre>
  
  <p>then I get this error message:</p>
  
  <pre><code>Traceback (most recent call last):

  </code></pre>
  
  <p>So, why I have this syntax error? I get that also when I am trying to install some package with pip3. </p>
  
  <p>Note:
  I have the following python versions installed:</p>
  
  <pre><code>$ python --version
  Python 2.7.3
  
  $ python3 --version
  Python 3.2.3
  </code></pre>
  
  <p>Best regards,</p>
