Building documentation fails with a Python import error

[ozkutuk]

Build of the documentation fails with the message provided in the "Actual behaviour" section. It fails regardless of the method used for building the documentation (i.e. both with nix build .#docs and with cd docs; make html).

Debug information

The error thrown by Nix probably indicates a bug in our nix files.

Meanwhile, when not using Nix, you need to use pip install -r requirements.txt to install the dependencies first. You may use something like venv to prevent the python libraries from being installed globally.

Contributions welcome!

Is there a particular reason for not using the myst-parser and sphinx_rtd_theme packaged on nixpkgs? It seems like there is an issue with packages provided through poetry2nix. I have replaced those two with their nixpkgs counterparts and documentation built successfully (well, it still failed but that's unrelated to the nix issue, caused by a sphinx warning promoted to an error).

Looks good to me ;)
