 adisbladis | You could also not use flakes? | 22:45:27 |
 rpop0 | What would be the alternative? nix-shell? | 22:46:11 |
| adisbladis | In reply to @rpop0:matrix.org
What would be the alternative? nix-shell? Yes, nix-shell | 22:47:03 |
| adisbladis | https://github.com/edolstra/flake-compat might be an option if you still want to express yourself as a flake, but eval using nix-shell. It still does the whole fetchGit thing iirc, so you'll have to provide it with a source that doesn't look like a git repo | 22:47:57 |
| rpop0 | So just to understand, for example in a project when using a flake that would be for setting up a more general environment to be used by everyone. On the other hand, if I need something set up just for myself (Or I'm the only one interested in using nix), a nix-shell would be the better solution? | 22:52:07 |

Flakes and nix-shell are morally equivalent (see https://jade.fyi/blog/flakes-arent-real/ ) | 22:59:51 |
| rpop0 | Like in my specific case, only me and 2 other team members are doing our development in a linux environment, while the rest of our team are on windows. Out of the 3 of us on linux, I'm the only one interested in nix and configuring my environment that way, so I'd rather not bother other people with my configurations and things | 23:00:09 |
| adisbladis | The reason why I'm suggesting nix-shell here is because it doesn't have strange special behaviour re git | 23:00:27 |
| rpop0 | Alright, I'll look into that | 23:01:17 |
| rpop0 | Thanks | 23:01:55 |

Yep, it's definitely something to do with the wrong Python version - I see mention of Python 3.12 in pre-commit output, and both mypy and pylint complain about missing libraries which are installed in the poetry2nix package set. Also:
❯ type -a python
python is /nix/store/d6cy7nfpwjppghqg3mav9537ypl6ww82-python3-3.11.9-env/bin/python
python is /nix/store/pgb120fb7srbh418v4i2a70aq1w9dawd-python3-3.12.5/bin/python
Any idea why this could be? I don't have Python installed at the OS level:
❯ python --version
The program 'python' is currently not installed. It is provided by
several packages. You can install it by typing one of the following:
It's even easier to see the issue in this PR.

| l0b0 | Or even easier than that, check out master and apply this diff:
diff --git a/python.nix b/python.nix
index 2c252db..64d5494 100644
--- a/python.nix
+++ b/python.nix

{pkgs}:
-pkgs.python3
+pkgs.python310
With the old version of nixpkgs it builds, you get both Python 3.10 and 3.11 in the resulting shell.

| l0b0 | On a related note, How to figure out which part of a derivation is pulling in a specific store path? | 20:15:13 |
| l0b0 | Hmh, after a bit of manual shenanigans it looks like all of black, check-jsonschema, gitlint, and nbqa pull in the Python executable. Dang. But also, nothing to do with poetry2nix. | 20:31:13 |
| l0b0 | * Hmh, after a bit of manual shenanigans it looks like all of black, check-jsonschema, gitlint, and nbqa pull in the Python executable. Dang. But also, nothing to do with poetry2nix. But now I need to wire a bunch of packages to the same Python I use in the poetry2nix package set, otherwise I can't run things like mypy. | 20:38:14 |
| l0b0 | I've tried to instead patch the third party packages to support Python 3.12, but now I'm running into another issue with GDAL: "error: value is null while a set was expected" because nativeBuildInputs is null somehow. | 21:55:39 |

| l0b0 | Excluding that part of the derivation, I run into yet another issue: "ModuleNotFoundError: No module named '_cffi_backend'" when building argon2-cffi-bindings. I've tried adding cffi to buildInputs, nativeBuildInputs, and propagatedBuildInputs, with no change in the error message. | 22:28:57 |
| l0b0 | Turns out argon2-cffi-bindings doesn't build on Python 3.12 | 22:56:19 |
| l0b0 | * Turns out argon2-cffi-bindings doesn't build on Python 3.12, which in turn breaks jedi and then numpy. | 22:59:22 |
| l0b0 | OK, I give up. I've been trying to update nixpkgs for two days now, and I keep getting new and weird error messages. | 23:53:01 |

| wecmyrc | Hi everyone, I was trying to build a program using nix build and encountered an error: "[Errno 2] No such file or directory: 'git'". I tried adding setuptools-scm to nativeBuildInputs, but it didn't help. Has anyone run into this issue before? | 17:55:28 |
