title: RaspBerry doesn't find pip3
body: <p>I installed Python 3.4 with <a href="https://linuxconfig.org/how-to-change-from-default-to-alternative-python-version-on-debian-linux" rel="noreferrer">this website.</a> (I installed it with sudo apt-get python3.4)</p>
  
  <p>IT finished without any problems and if I type:</p>
  
  <pre><code>python --version
  </code></pre>
  
  <p>I get back:</p>
  
  <pre><code>python 3.4.4
  </code></pre>
  
  <p>But if I then want to make something with PIP3 it says:</p>
  
  <pre><code>-bash: pip3: command not found
  </code></pre>
  
  <p>Trying it for pip brings the same.</p>
  
  <p>I need pip3 to install <a href="https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/installing-circuitpython-on-raspberry-pi" rel="noreferrer">Adafruit-Blinka</a></p>
  
  <p>What can I do?</p>
  
  <p>I also tryed:<code>sudo apt-get install python-pip</code>
  This installs normal pip, there seems to be no install for pip3.</p>
  
  <p>Thanks!</p>
