Work with Python "normally" on NixOS in one command!

Tired of all these "*.so not found" errors? Change the RPATH of all the binaries in your venv!

• Nix
• nix-command and flakes experimental features must be enabled

Use temporarly in a shell

nix shell github:GuillaumeDesforges/fix-python

Or add it to your profile

nix profile install github:GuillaumeDesforges/fix-python

In your Python project, create a virtual environment .venv and use your preferred tool (pip, poetry, ...) to install your dependencies.

Then create a .nix/libs.nix file that returns the array of packages that you want binaries to be linked with.

Note: you may add this .nix folder to your project .gitignore.

let pkgs = import (builtins.getFlake "nixpkgs") { };
in [
  pkgs.gcc.cc
  pkgs.glibc
  pkgs.zlib
]

Note: these three packages are fundamental for most Python packages and should never me removed.

Finally, call fix-python.

fix-python --venv .venv --libs .nix/libs.nix

See the list of options with

fix-python --help
