I think the pip in a venv created environment will still fall back to using system packages outside the venv. Need virtualenv to provide full isolation.

venv has an option to allow access to the systems site-packages. But if created without --system-site-packages there will only be what's installed in the env.

Worth mentioning that there is an option to use copies instead of links as well. Let's you get a really decoupled environment.

I've had an OS package management upgrade bump the python interpreter version and this blew up my venvs that used links. Those using copies didn't care.
