tl;dr: how can I install optional sage packages on archlinux?
Quoting the Arch wiki page for sage:
Most if not all of the standard sage packages are available as Arch packages and exposed as (optional) dependencies of sagemath, so there is no need to install them with
Alas, the (very) nauty package is an optional one, and so cannot be installed from with pacman.
The error I get when trying the standard
sage -i nauty (either with or without sudo) is
/usr/bin/sage: line 297: ./sage: No such file or directory
This is documented in the talk page (of the Arch Wiki) for Sage (as in "this happens"). That page does not discuss workarounds.
So far I have been unable to find any reference or guidance in installing optional packages.
Any reference would be warmly welcomed!
