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

This project supports the following Python versions:

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

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

Install Cachix and run:

$ cachix use nixpkgs-python

Add to your devenv.nix:

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

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=";
  };
}

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

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

{
  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"
  };
}

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"'
