Using python.withPackages with nixpkgs-overlays does not work #26487
Description
Issue description
I'm currently trying to make python.withPackages work with some custom overlays, but can't find to make it work.
Steps to reproduce
~/.config/nixpkgs/overlays/test.nix
self: super: with self;
{
pythonPackages = super.pythonPackages.override {
overrides = self: super: {
my_stuff = pythonPackages.buildPythonPackage rec {
pname = "pyaes";
version = "1.6.0";
name = "${pname}-${version}";
src = pythonPackages.fetchPypi {
inherit pname version;
sha256 = "0bp9bjqy1n6ij1zb86wz9lqa1dhla8qr1d7w2kxyn7jbj56sbmcw";
};
};
};
};
my_stuff = pythonPackages.buildPythonPackage rec {
pname = "pyaes";
version = "1.6.0";
name = "${pname}-${version}";
src = pythonPackages.fetchPypi {
inherit pname version;
sha256 = "0bp9bjqy1n6ij1zb86wz9lqa1dhla8qr1d7w2kxyn7jbj56sbmcw";
};
};
}nix-shell -p 'python.withPackages(ps: [ps.my_stuff])'
gives
error: attribute ‘my_stuff’ missing, at (string):1:91
(use ‘--show-trace’ to show detailed location information)
whereas nix-shell -p my_stuff works.
