virtualenv virtualenvwrapper virtualenv: error: unrecognized arguments: --no-site-packages

I am trying to upgrade python from 3.6 to 3.8. I was successfully using virtualenv/wrapper successfully (although only one environment and no bells, whistles, or hooks), but the upgrade has not gone smoothly. I deleted everything and tried to start again. I am trying to make a new environment with mkvirtualenv test, and I am now getting the error:

virtualenv: error: unrecognized arguments: --no-site-packages after it gives a man(ual) suggestion on how to invoke virtualenv, which leads me to believe virtualenvwrapper is working, but I've missed something.

Here are my details:

NB -

  • trying to install virtualenvwrapper it says version 4.8.4, but the online docs say it is in 5.x

--no-site-packages is the default for virtualenv (and has been for like 5 years?) you can remove export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages' from your .bashrc

it appears in virtualenv>=20 that this option was removed
