Yes, you can create a virtual env with all of the global packages. Though,
you would probably want to run:
`python3 -m venv ~/development/project/venv` to put the virtualenv files in
their own directory. Then you
just need to activate it with: `source venv/bin/activate`. As long as the
virtualenv is activated, you can interact
with it in the same way you would with the system/global environment. i.e.
running the interpreter will use the binary
from the virtualenv, pip install will install in the virtualenv only, etc.
