For a tarball like the one at pythonhosted you'd download the file and then run 'guix hash the-file'. If you're using a source code repository then from the top level of the repo you'd run 'guix hash --exclude-vcs --recursive .', or 'guix hash -rx .' for short. The hash layout that Guix uses is the sha256 of the tarball base32 encoded, but with a change in the letters used. For python packages you can specify a version number, so in this case it'd be 'guix import pypi jupyterlab_server/2.0.0rc1'. Some other importers us the '@' symbol to specify version number and I think some don't support using other versions at all. I don't know how compatible different major versions of jupyterlab-server are with each other, so I'd stick with 1.2.0 for now. > Regards, > Zelphir > > On 10/19/20 8:19 PM, Zelphir Kaltstahl wrote: > > > > Hello Efraim, > > > > Thanks for your patience!
