title: python virtualenv and Mac OS Monterey upgrade
body: <p>after the upgrade to Monterey virtualenvwrapper doesn't behave. I've tried uninstalling it and re-installing it, deleting the old workspaces.</p>
  <p>when I launch the mkvirtualenv this happens:</p>
  <pre><code>Using base prefix '/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7'
  New python executable in /venvdir/venvname/bin/python3.7
  Also creating executable in /venvdir/venvname/bin/python
  ERROR: The executable /venvdir/venvname/bin/python3.7 is not functioning
  ERROR: It thinks sys.prefix is '/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7' (should be 'my-project-dir/')
  ERROR: virtualenv is not compatible with this system or executable
  </code></pre>
  <p>whatever version of Python it's trying to use, from Cellar, is not working?</p>
  <p>in my ~/.bash_profile there is:</p>
  <pre><code>export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
  export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
  export WORKON_HOME=$HOME/.virtualenvs
  export PROJECT_HOME=$HOME/someworkspace
  source /usr/local/bin/virtualenvwrapper.sh
  </code></pre>
  <p>why is the python version is taken from &quot;Cellar&quot; rather than from VIRTUALENVWRAPPER_PYTHON.</p>
  <p>Another interesting this is that if I just run</p>
  <pre><code>python3 --version
  Python 3.7.3
  </code></pre>
  <p>But I thought Monterey was using 3.8.9?</p>
  <p>Does anyone know what has changed? Thanks T.</p>
  <p>EDIT: small update, I've rewritten the question since I had another problem which was solved by restarting. The python version problem still remains.</p>
