  <p>I am lost.  Thanks for any help</p>
  
  <p><strong>Update</strong></p>
  
  <p>I use venv to create virtual environments.  When no venv is activated, I can use pip3:</p>
  
  <pre><code>zeno:~/Desktop/tetris$ pip3 -V
  pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
  </code></pre>
  
  <p>but if I activate a venv, it does not work:</p>
  
  <pre><code>(.tetris) zeno:~/Desktop/tetris$ pip3
  Traceback (most recent call last):
    File "/home/zeno/Desktop/tetris/.tetris/bin/pip3", line 6, in &lt;module&gt;
      from pip._internal import main
  ModuleNotFoundError: No module named 'pip'
  </code></pre>
  
  <p>Thank you for your suggestions and continued help.</p>
  
  <p><strong>Update</strong></p>
  
  <p>I tried deleting the venv and making a new one, but it seems I need pip working in order to do that:</p>
  
  <pre><code>zeno:~/Desktop/tetris$ python3 -m venv .tetris
  </code></pre>
  
  <p>gives:</p>
  
  <pre><code>The virtual environment was not created successfully because ensurepip is not
  available.  On Debian/Ubuntu systems, you need to install the python3-venv
  package using the following command.
  
      apt-get install python3-venv
  
  You may need to use sudo with that command.  After installing the python3-venv
  package, recreate your virtual environment.
  
  Failing command: ['/home/zeno/Desktop/tetris/.tetris/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']
