scatac_fragment_tools fails to build while building a Docker image for SCENIC+

[mestia]

rustc version comes from python:3.8-slim which is based on Debian bookworm.
Any hint how to fix that? Thanks!

Hi @mestia

I'm afraid you will need a docker environment with rustc version 1.65 or higher.
You could consider trying cargo update -p regex-automata@0.4.5 --precise ver "where ver is the latest version of regex-automata supporting rustc 1.63.0" as suggested in the error message, however I can not guarantee that this will work.

We are releasing the package to pypi soon, that way you may not need to build it from source. So stay tuned for that.

All the best,

Seppe

scatac_fragment_tools is now on PyPI:

pip install scatac_fragment_tools

Great! I have managed to build the docker image for scenicplus buy using Trixie (Debian testing) which comes with rust 1.70.
