Thanks for reporting, I need to investigate this. There is a build target documentation that should create the missing documentation. As a workaround, you may build this target before installation.

Is my sphinx installation incomplete?

Yes, sphinx_copybutton is a plugin that is not bundled with Sphinx.

@VictorEijkhout Please let me know if this issue still exists after my commit bd3ce91.

Confirm fixed.
