not able to install on NixOS

[turbotimon]

I tried all the possibilities on the README

The easiest method to try is by installing directly:

$ nix-env -i -f https://github.com/vlaci/openconnect-sso/archive/master.tar.gz
installing 'python3.11-openconnect-sso-0.8.1'
trace: warning: `pythonForBuild` (from `python*`) has been renamed to `pythonOnBuildForHost`
trace: warning: `pythonForBuild` (from `python*`) has been renamed to `pythonOnBuildForHost`

RAM gets completely full (32GB), nothing happens..

An overlay is also available to use in nix expressions: My shell.nix looks like:

# shell.nix
let
openconnectOverlay = import (builtins.fetchTarball "https://github.com/vlaci/openconnect-sso/archive/master.tar.gz") + "/overlay.nix";
pkgs = import <nixpkgs> { overlays = [ openconnectOverlay ]; };
in
pkgs.mkShell {
# Now pkgs.openconnect-sso will be available in the shell environment.
buildInputs = [ pkgs.openconnect-sso ];
}

Same error and behaviour like above

I also tried pipx but that does not work on nix because of PyQt6 can't be installed the normal way.

Anyone can help to fix this?

NixOS Version 24.05

I'm getting in the same situation with the nix-env method but with the second method I actually get a build error:

error:

       error: poetry2nix is now maintained out-of-tree. Please use https://github.com/nix-community/poetry2nix/

My NixOS version is also 24.05.

You need to add the community maintained version of poetry2nix to pkgs

I added this to my inputs:

poetry2nix = {
            url = "github:nix-community/poetry2nix/2024.5.939250";
            inputs.nixpkgs.follows = "nixpkgs";
          };

And made the packages

        config = { 
          allowUnfree = true;
          packageOverrides = _: {
          poetry2nix = poetry2nix.lib.mkPoetry2Nix { inherit pkgs; };
          };
         };

Then i also had an issue where a python didn't build because it required a higher version of another - this is fixed if you get the overlay from my fork

@arthur-d42 thanks for your message! I'm not exactly sure where to put the config = part. Do you mind share the whole shell.nix? (btw, your link does not point to the link text)
