# Can't find packages combinat and cluster

I just installed SageMath-8.1.app on MacBook Touchbar OSX 10.12.6. I wanted the ClusterAlgebra/Quiver package. The 2011 manual ("Compendium") says to first install the combinatorics package "combinat " by entering "./sage -combinat install". I did that on the terminal command line in various subdirectories of SageMath-8.1.app but got only error messages. I then tried "./sage -i combinat" which produced much output with the upshot that it couldn't find combinat. "./sage package list" showed neither combinat nor anything sounding like "cluster". I will appreciate suggestions. ---If this is not the right forum for this question, please advise where to go. Thanks.

Can you say exactly where you found this 2011 manual? It may be quite out of date. The combinat part definitely is not accessed that way now. However yes, this is the right place to ask this question!

Thanks. I googled 'cluster algebra computer package' and that 2011 manual was the first hit. From there I was directed to combinat and sage. I knew nothing about sage (still don't) so got nowhere.
