title: how to make mkvirtualenv work with current directory?
body: <p>I'm trying to use <code>mkvirtualenv .</code> to create a virtualenv in the current directory, but with no success:</p>
  <pre><code>~/repos/foo$ mkvirtualenv .
  created virtual environment CPython3.9.5.final.0-64 in 284ms
    creator CPython3Posix(dest=/Users/mdval/.virtualenvs, clear=False, no_vcs_ignore=False, global=False)
    seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/Users/mdval/Library/Application Support/virtualenv)
      added seed packages: pip==21.2.3, setuptools==57.4.0, wheel==0.37.0
    activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator
  ERROR: Environment 'foo' does not exist. Create it with 'mkvirtualenv foo'.
  </code></pre>
  <p>However, using <code>mkvirtualenv foo</code> works. Can someone help me, please?</p>
  <p>Here's my <code>.zshrc</code> config:</p>
  <pre><code>export WORKON_HOME=$HOME/.virtualenvs
  export PROJECT_HOME=$HOME/repos
  export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
  source /usr/local/bin/virtualenvwrapper.sh
  </code></pre>
