nixpkgs-python

All Python versions, kept up-to-date on hourly basis using Nix.

Supported Python Versions

This project supports the following Python versions:

• 2.7.6+
• 3.3.1+ (up to the latest release)

Caching (optional)

Use the Cachix binary cache to avoid rebuilding Python from source.

System-wide

Install Cachix and run:

$ cachix use nixpkgs-python

devenv

Add to your devenv.nix:

cachix.pull=["nixpkgs-python"];

Flake

Add the cache substituter and public key to your flake.nix:

{nixConfig={extra-substituters="https://nixpkgs-python.cachix.org";extra-trusted-public-keys="nixpkgs-python.cachix.org-1:hxjI7pFxTyuTHn2NkvWCrAUcNZLNS3ZAvfYNuYifcEU=";};}

Note

Do not override the nixpkgs input when using this flake. The cached builds are tied to the pinned nixpkgs revision; overriding it will result in cache misses and local rebuilds.

To push your own builds to the cache (useful in CI or team setups), create a Cachix account and configure a push workflow so builds are cached as they happen.

Supported platforms:

• x86_64-darwin
• x86_64-linux
• aarch64-linux
• aarch64-darwin

Usage

devenv.sh

Create devenv.nix:

{pkgs, ... }:
{languages.python.enable=true;languages.python.version="3.11";# languages.python.version = "3.11.3";}

Create devenv.yaml:

inputs:
nixpkgs-python:
url: github:cachix/nixpkgs-python

Then run:

$ devenv shell

flake.nix

{inputs={nixpkgs-python.url="github:cachix/nixpkgs-python";};outputs={self,nixpkgs-python}: {# You can now refer to packages like:# nixpkgs-python.packages.x86_64-linux."2.7"};}

nix shell

You can run this package ad-hoc using the following command:

$ nix shell github:cachix/nixpkgs-python#'"2.7"'

Or specify a minor version:

$ nix shell github:cachix/nixpkgs-python#'"2.7.16"'
