By default running "sage -i normaliz" in Sage 8.9 installs Normaliz version 3.7.2 How one can install a newer version 3.8.0 instead?
Relatedly, if Normaliz was already installed, is there a way to reinstall its newer version?
The short answer is no, since the package versions of optional packages are hardcoded into each Sagemath version, so that the behaviour is predictible.
So if you want to have normaliz 3.8.0 (or 3.8.1) installed within Sage, before some Sage release proposes it, you will have to modify SAGE_DIR/build/pkgs/normaliz/package-version.txt and SAGE_DIR/build/pkgs/normaliz/checksums.iniyourself. See https://doc.sagemath.org/html/en/deve... for more details.
If this is beyond your skills and you need some feature that exists in 3.8.0 and not 3.7.2, please tell us, and i (or some other developer) will update the package quickly.
Thank you for the answer, I was able to successfully install the current version (3.8.5) of Normaliz with the current Sage 9.1 per your instructions. At the same time, I was unpleasantly surprised that Sage 9.1 comes with the same old Normaliz version 3.7.2. Newer versions are almost always desirable because of bugfixes and speedups they offer. It is sad that third-party packages are not brought to the up-to-date state with each Sage release.
