That's just a general issue with Nix shells and things that try to install things

In reply to @k900:0upti.me
Either you let Poetry manage everything or you let Nix manage everything

I am trying to install packages with poetry but running into permission errors.

~/Projects/nix-poetry(branch:dev*)(nix-shell)$ poetry add flask

I have a shell.nix that looks like this:

{ pkgs ? import <nixpkgs> {} }:

with import <nixpkgs> {};
let pythonEnv = python38.withPackages (ps: with ps; [
flake8
black
pynvim
ipython
python-language-server.override { pylint = null; }
pip
poetry
]);

in
pkgs.mkShell {
buildInputs = with pkgs; [
pythonEnv
];
}

I was trying to follow this video of using poetry and nix - https://www.youtube.com/watch?v=TbIHRHy7_JM

If you manage to allow poetry create venv, then all should be according to video

Can we use pyproject.toml build tool metadata to detect which one is used for dependency (if such dependency fetched in form of source), and include this tools in build dependencies?

adisbladis: as promised i made a small document on my solution for building with missed poetry build tool. I'm not insisting on this is appropriate structure or content to include in repository, but it's contains information i really like to get when encountered such problem. Feel free to use it (or not use at all) whatever way you like.

Suggestions from everyone else also welcome.

Text may contains many grammatical mistakes, so i'm really appreciate if anyone point them out.

In reply to @mou_bugtracker:matrix.org
Also i can fix whatever way you suggest and prepare PR if needed

In reply to @adis:blad.is
I don't really have much feedback except that it looks great!
Please PR this 👍️

How to name file and where to put it? In root? I have doubts about in-lining it in README

Hey folks! I'm at my wits end here, trying to use Nix to manage my python project in any capacity. I have two questions: a specific one and a general one:

• specific: I have set up a basic mkPoetryEnv in shell.nix, but when I try to actually start the shell, all I get is error: Missing suitable source/wheel file entry for tensorflow. Couldn't figure out what could cause this, so I'm stuck.
• general: Is poetry2nix even the right tool for what I want to do? So my setup right now (without nix) is: I have a couple of repos I work in and edit; so I have a pyproject.toml that lists them as dependencies by local paths, plus some more dependencies just from pip. Some of these dependencies come from a private pypi server, which is also listed in pyproject.toml. Can poetry2nix handle this relatively simple usecase?
  -- complication 1: can I add some packages without including them in the pyproject.toml? e.g. I don't really want Jupyter to affect the dependency resolution process.
  -- complication 2: what if I also want to add some non-python packages to the environment (say, tmux)?

Sorry for the wall of text, just really frustrated so far with how little of Nix is documented properly and how untransparent the whole ecosystem in general is 🙃
