----------------------------+--------------------
 i recently updated my macports base from 2.6.4 to 2.7.1 and, with this, my
 installation of pipenv. In my environment i use python38 as default
 python3 installation, so all of my virtualenvs are created for this
 version of python. I ran pipenv and it fails immediatly with this error

 }}}


 since the error involes virtualenv, i tried to switch to virtualenv39 via
 {{{sudo port select --set virtualenv virtualenv39}}}. The error persists.
 Launching virtualenv (3.9) by command line successfully creates a new
 environment.

 I tried to reinstall a previous version of pipenv ( @2020.8.13 ) but it
 shows me the error message {{{Error: pipenv version 2020.8.13 is not
 available (current version is 2021.5.29_0)}}}
