jupyter is an (undeclared) build-time dependency

[QuLogic]

The chain unconditionally goes meson.build -> examples/meson.build -> examples/notebooks/meson.build, and in the last file is a call to find_program('jupyter'). But this defaults to required:true, meaning that that program is required to build. However, it is not listed in the build-system.requires entry in pyproject.toml. It also isn't in the runtime dependencies or, e.g., a "test" optional dependency list.

If you're building a normal (non-editable) install, then build isolation is enabled, but it won't affect $PATH, so this probably snuck by. But if you're building in a completely clean environment (cibuildwheel, distro packages, etc.) that just install what's in the metadata, it will fail.

I confirm this problem.

[MarkWieczorek]

This is fixed in the develop branch, and I'll be merging this to master next week.

[vianamp]

Thank you. Also, not related but, can you please tell me if you ever tried to install pyshtools using Python 3.11?

[MarkWieczorek]

Are you having a problem with 3.11? It should work.

[vianamp]

Yes, I can only get pyshtools installed in 3.11 if I pin the version to 4.10.4. I am running ubuntu 18.04.

[MarkWieczorek]

Could you please open a separate issue, and provide all the necessary details to reproduce and debug this problem? Please also be aware that there are several issues open regarding 4.11 because there is no wheel or conda package available at this time. At this point, installing via pip will install from source, and you will need to install the necessary dependencies.
