If I understand correctly, either you install SageMath from source and then you can use "sage -i ..." to install extra packages, or you install SageMath from some package manager, e.g. from the Ubuntu package manager, and then if you want FriCAS you need to install it on its own, make sure it's in the PATH, and then Sage should be able to talk to it. FriCAS does not seem to be packaged in Ubuntu, https://packages.ubuntu.com/search?keywords=sagemath https://repology.org/metapackage/fricas/versions but the Fricas documentation page http://fricas.sourceforge.net/doc/ has links to "install from source" and "install from binaries": http://fricas.sourceforge.net/doc/INSTALL.txt http://fricas.sourceforge.net/doc/INSTALL-bin.txt -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

FriCAS does not seem to have a package in the Debian and Ubuntu
repositories at the moment, but axiom does.
Other than that, I assume it will be possible to use another install of
FriCAS using sage.interfaces.fricas just by adjusting the command there
(not tested):
sage: new_fricas = FriCAS(command="/path/to/new/fricas -nosman")
sage: new_fricas("1+1")

Try and see if sage -i fricas works.

[sage-devel] Re: FriCAS and Sage Math v8.1 Ubuntu package
Thank you. I suspect you are right.
I am right to think that installing packages in this way requires that I
have compiled Sage Math from source? In that case, I may need to switch
from the binary version in the Ubuntu repositories back to compiling from
source.

[sage-devel] Re: FriCAS and Sage Math v8.1 Ubuntu package
FriCAS is an optional Sage package, so it is not automatically installed.
If you have built from source, you can easily install it (with "sage -i
fricas"), and maybe that's what you did before.
