Bug 686762 – dev-python/jupyter_console-6.0.0: Could not import extension sphinxcontrib_github_alt (exception: No module named 'sphinxcontrib_github_alt')

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Hamlet 2019-05-25 21:25:02 UTC]

It looks like `dev-python/jupyter_console-6.0.0` with `USE=doc` uses some sphynx feature that requires `dev-python/sphinxcontrib-github-alt` or so. Output of:

--- 8< ------------------------------------------------------
# emerge -1upv --nodeps dev-python/jupyter_console

These are the packages that would be merged, in order:

Confirming that when `dev-python/sphinxcontrib-github-alt` is installed, `dev-python/jupyter_console-6.0.0` also merges successfully with `USE=doc`.

I confirm: jupyter_console-6.0.0 fails to build without dev-python/sphinxcontrib-github-alt. The relevant snippet of error message is at the end of this message.
The obvious fix is to add sphinxcontrib-github-alt works. It builds successfully with this very simple change applied to an ebuild ebuild:
