pkgx: youtube-dl not executing

I got the below error when running trying youtube-dl -h in addition to just youtube-dl. I think this is an issue when you try to set PYTHONHOME & PYTHONPATH when they are not needed, or with the virtual environment config.

Took some digging but I figured it out. Thanks to these repro instructions:

$ docker run -it --rm ubuntu
[ now in docker ]
# apt update && apt install -y curl && sh <(curl https://tea.xyz) -y
[ ... ]
# tea poetry --version
[ error ]
# rm -rf ~/.tea/python-poetry.org
[ clean install ]
# export TEA_PREFIX=~/.tea
# tea poetry --version
[ success! ]

The issue is that these lines in python-venv.sh assume the presence of the TEA_PREFIX environment variable, which apparently does not exist in certain clean installs. Not sure if this assumption is incorrect or if this isn’t getting passed to subcommands within the tea command environment.

In case I’m not clear, I’m very eager to figure out the issue. I’m pondering it. Any more info you got will help.
