The ore-algebra project, unfortunately, does not make proper releases; the Sage package is keyed to a particular commit in the project's github. $ cat build/pkgs/ore_algebra/requirements.txt git+https://github.com/mkauers/ore_algebra@6826ac49b4cdf66a563449aced21a2fd1fd085c9#egg=ore_algebra You can help by convincing the project maintainers to follow the best practices for Python packages: making releases and publishing them on PyPI.

It uses the following version specification: $ cat build/pkgs/jupyterlab/requirements.txt jupyterlab ~= 2.2.5 I would hope that in the Sage 9.4 series, we can upgrade ipython/jupyter/jupyterlab. There is already a ticket for this task: https://trac.sagemath.org/ticket/31280 – help is welcome. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
