title: pip install & uninstall recursively in non-interactive mode
body: <p>As a part of my bash script, I want to install and uninstall pip dependencies that I have their names in a file in a non-interactive mode. I was able to search around and find these commands: </p>
  
  <pre><code>pip3 uninstall --yes -r host-requirements.txt
  pip3 install --no-input -r host-requirements.txt
  </code></pre>
  
  <p>I wasn't able to find <code>--yes</code> &amp; <code>--no-input</code> options in the help doc of pip, and I'm not sure if they are officially supported.</p>
