Using PythonKit with a python virtual environment

[MisterDrgn]

Hi all. I just got PythonKit working, which required providing a path to my python library.

PythonLibrary.useLibrary(at: "/Library/Frameworks/Python.framework/Versions/3.12/Python")

I'm wondering if anyone knows how to get PythonKit to use a virtual environment created with venv (or any other python tool), given that they don't create their own library?

Thanks.

Does this help?

Unable to use python modules that are installed on my mac with PythonKit

I think that the error isn't saying what you think it's saying. I think that PYTHON_LIBRARY isn't the path to the external pip package libraries - it's looking for the path to the library for Python itself. Anyway - you may have better luck trying the other approach (use the version of Python that PythonKit is already finding). It worked for me. When I installed Python via brew and attempted to install some packages via pip I was warned that: × This environment is externally managed If …

Thanks. That certainly appears reasonable. In an ideal world, I'd like to have a fully encapsulated development environment with its own version of python and its own installed packages that may or may not overlap the ones installed on the system. I'm used to doing that on linux with docker, and I believe you can do that with venv and related tools. But perhaps that isn't an option. At least your approach provides a straightforward means to install packages without affecting the host system.
