I don't want to make the
venv
portable...I want to use the
gunicorn
that is installed in onevenv
accessible to othervenv
I don't think that's possible without some dirty, dirty hacks i.e adding the right paths from the other
venv
to your running process. Do you want dirty hacks? Because that's just asking for trouble. If you have an application that requireslibA-v1
and the gunicornvenv
useslibA-v2
, you're going to have a conflict at runtime.gunicorn
takes a module and a module name with a variable name. Modules are found by searching in specific paths. You can add to that search path by modifying PYTHONPATH. How it works is explained here (quite wordy).To know which path to add to
PYTHONPATH
, you can either read.bin/activate
and figure it out, or run something likebash -c "source ./bin/activate ; env"
and it'll list all the environment variables. You can then expand (not replace) the environment variables of the current environment with those of the other environment - either inbash
or inpython
- up to you.As I said, dirty dirty and honestly I'd just install
gunicorn
in everyvenv
then you're done with it. But if you really want to, try what I explained and see how it works for you. It's good to experiment and find out first hand.Anti Commercial-AI license
Wouldn't enabling the
--system-site-packages
flag during venv creation do exactly what the OP wants, provided that gunicorn is installed as a system package (e.g. with the distro's package manager)? https://docs.python.org/3/library/venv.htmlSharing packages between venvs would be a dirty trick indeed; though sharing with
system-site-packages
should be fine, AFAIK.Hadn't considered that. It might be the solution @SpongeB0B@programming.dev is looking for. Good shout.

Why? How many kilobytes of disk space are you going to save from that?
