Perhaps that will help the tests pass. The thing is, that I already tried to run the tests within the jupyterlab_server repository and they do not pass there either. They are simply failing currently / jupyterlab_server stable is not in a clean state. At first I had to figure out how to get a test environment set up, but I solved that one: https://github.com/jupyterlab/jupyterlab_server/pull/129. I think there is nothing on the Guix side to make them magically pass, when they even fail in the original repository / code. Where do you grep for add-installed-pythonpath in other packages? I have looked here https://git.savannah.gnu.org/cgit/guix.git/tree/guix/packages.scm, but that seems to be the package implementation of Guix itself, not the packages it offers. Ah, I think I found it: https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages.
