My bad, it's probably not a good idea to have that without containers, 
as it execute some code that we don't know what it does - the setup.py. 
The best way to go is to parse the setup.py *and* requirements.txt.

I attached a script that does what I described without the `guix 
environment`.

Using `guix environment` might be a good idea to prepapre a recipe 
without polluting its own profile.

HTH.
