title: pip keeps pointing to python 2.7 instead of 3.7, on raspbian/ubuntu
body: <p>I have installed python3 on my raspberry 4, and i guess there is a native python2 as well. I must use a library that needs python3.6+, and it checks the version of pip (not pip3!) and if it finds out that it points to python2, it throws an exception. My pip command is stuck pointing to python2.7 and I would like it to point to python3 instead. I've tried many things from other answers:</p>
  <pre><code>python -m pip install --upgrade --force-reinstall pip
  </code></pre>
  <p>and</p>
  <pre><code>pip3 install --upgrade --force pip
  </code></pre>
  <p>then</p>
  <pre><code>python3 -m pip install --upgrade --force pip
  </code></pre>
  <p>None of the above changed the behaviour, and I still get this when i run <code>pip -V</code>:
  Warning: pip is being invoked by an old script wraper...[...]</p>
  <blockquote>
  <p>pip 20.02 from /home/pi/.local/lib/python2.7/site-packages/pip (python
  2.7)</p>
  </blockquote>
  <p>What can I do? Thanks</p>
