Thanks! with this config in the readme, I have got the same error.

Hi. I'm getting the following error when trying to build my application via flake:

error: hash mismatch in fixed-output derivation '/nix/store/fygngq683zgps12zy1063gbq8vsjzvzm-cryptography-41.0.7-vendor.tar.gz.drv':
         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=

I read about this issue, but I'm using a flake and made sure the revision for poetry2nix in flake.lock matches the HEAD commit in the master repo. Any ideas what could be wrong?

I'd like help to understand editablePackageSources.

I've defined on my flake.nix:

        cexpl-py = (p2n.mkPoetryEnv {
          projectDir = ./.;
          editablePackageSources = {
            cexpl = ./.;
          };
          overrides = p2n-overrides;
        }).env.overrideAttrs (oldAttrs: {
          buildInputs = dependencies;
        });

and I'm able to import my package:

❯ python3
Python 3.11.6 (main, Oct  2 2023, 13:45:54) [GCC 12.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cexpl
>>> cexpl
<module 'cexpl' from '/nix/store/vj18qa9acmghnipqx98x94fqbhg1vcdq-source/cexpl/__init__.py'>
>>>

But it shows up inside the nix store, which is read-only. So, how could it be "editable"?

pip show outputs:

Are you using flakes?

In reply to @k900:0upti.me
So they don't know where they've been copied from

Add cmake to nativeBuildInputs

Thanks! Now I first get a cmake warning:
Ignoring extra path from command line:
".."

Then a cmake error:
The source directory "/build" does not appear to contain CMakeLists.txt

Yeah I suppose, simplejpeg seems pretty obscure... It does compile if I use preferWheels. obviously that is not optimal, but if it works 🤷‍♂️
