Meanwhile I have managed to run the jupyterlab-server tests, as
described in more details here:
https://github.com/jupyterlab/jupyterlab_server/issues/128
Indeed, in version 1.2.0 the tests fail the same way they fail when I
try to create my environment. This means the next thing to fix would
probably be to use another version of jupyterlab-server. 1.2.0 is a tag
in the jupyterlab-server repository, which _seems_ to be the latest
"stable" version, before a lot of alpha, beta, and release-candidate
versions follow.
I guess I could switch the commit in my `jupyterlab.scm` file to point
to a different one?
I can change the version to `2.0.0rc1`, but I do not know how the
checksum is calculated. The checksum is shorter than what I see on
simply PyPI:
https://files.pythonhosted.org/packages/79/43/5249be5ee741a93f3fa60823caf9a276cadc3103dae16d6e36cc534fefd8/jupyterlab_server-2.0.0rc1.tar.gz#sha256=733b149c5ab8e50ea5f2897c323047257060e7bf2dc0fa88663181427bec605d
and base32 should only make it longer, not shorter.
Can you explain how to switch a version manually and calculate the
checksum to match another version?
Regards,
Zelphir
