any ideas why this is happening?

Hi @Bergrebell,

looks like this is related to Pipenv and not to this project. However, we replaced Pipenv with Poetry some time ago for dependency management. If you have checked out the latest master branch of this repo, you can run poetry install to install all dependencies.

I have just seen that the README is outdated and recommends using Pipenv. I'll update this – thanks for reporting :)
