pip2nix
Noted: Latest version of pip2nix only use python39. While nixpkgs 22.11 (current stable) is python310. I dont to install multiple versions of python3.
If pip2nix can overcome the disadvantage of that generate a long list of python packages, and reuse python3Packages in nixpkgs, I would prefer to use pip2nix completely.
Currently, I use buildPythonPackage.
buildPythonPackage
pkgs.python3Packages.buildPythonPackage
venv
Use virtualenv, pip is available, no need to write nix expressions to install packages.
Code see https://xieby1.github.io/scripts/index.html#venvnix
poetry
According to What is the correct way to setup pip with nix to install any python package in an isolated nix environment, I found two useful tools to install python packages in Nix/NixOS
- [TODO] poetry
- mach-nix
mach-nix
mach-nix github repo: github.com/DavHau/mach-nix
Here is [python_mach.nix]({{ site.repo_url }}/scripts/shell/python_mach.nix), an example which create a shell with a python package called expmcc.
