I don't know if I have some misunderstanding of how tlmgr works, but I can't get it to install packages.
I want to install this package here, so I do
sudo tlmgr install diagrams
but I get
tlmgr install: package diagrams not present in repository.
I couldn't tell if this was because this was a collection, so I tried installing the more specific package inside it here,using
sudo tlmgr install taylor
but the same message appeared.
diagramsis a collection of generic macro packages, which are individually available in TeX Live as well as MiKTeX. See this page on CTAN. – Bernard May 09 '19 at 21:11taylorpackage is not in TeX Live - the package is a bit strange, the code is mostly (intentionally) obfusciated by the author, and there is a notion of a 'time bomb' which is a date after which the package does not run, and the author of the package is also not really community-minded (see https://tex.stackexchange.com/a/176573). You can install the package manually if you want - but there are also other more modern packages with good documentation and many features available, such astikz-cd(which is in TeX Live). – Marijn May 09 '19 at 21:23
