I got something similar with babel

My error is:

I guess mach-nix isn't case-sensitive here?

cscutcher · 2022-07-15T11:58:50Z

@gador I'm seeing that issue too, and while the error does look the same, I think the cause might be different.

I think the root of the problem you and I are seeing is that python-aliases.nix in the official nixpkgs added the alias from Babel to babel (it is case sensitive). However, in the generated overrides that mach-nix creates during build, it does;

    "babel" = override python-super."Babel" ( ... )

which means that Babel refers to babel which refers to Babel 💥😭.

I'm no expert when it comes to nix though, and mach-nix is super clever, but pretty complicated so I could definitely be wrong. If someone who knows better can confirm, then I'll create a different issue for the problem @gador and me are seeing. (My full trace output is in this gist)

(@gador I did poke around trying to work around the problem but didn't have much luck. That being said, if you are able to pin to a version of nixpkgs before 2022-05-06 you can probably avoid the issue if that helps. Unfortunately for me I need to be on a newer nixpkgs for other reasons 😔 )

cscutcher · 2022-10-27T19:40:32Z

I happened to come across this again today. Setting this for the overridesPre;

    overridesPre = [
      (self: super: {
        _babel = super.babel;
      })
    ];

and overridesPost to include;

    overridesPost = [
      (self: super: {
        babel = self._babel;
        Babel = self._babel;
      })
    ];
``

helped as a workaround

Worth pointing out this bug can also look more like this;

from nix-community/poetry2nix#750 (thanks lelit for linking to that issue!)

Works around nix-community/poetry2nix#750 > infinite recursion encountered The issue, as pointed out in DavHau/mach-nix#470 (comment), is that nixpkgs defines ``` Keras = keras; ``` https://github.com/NixOS/nixpkgs/blob/fbb042bc87bc92fc5296b8b151e36970dd996c64/pkgs/top-level/python-aliases.nix poetry2nix must (somewhere) set `keras` to depend on `Keras` meaning infinite recursion. The fix is based on the code in nix-community/poetry2nix#750 (comment)
