Sage won't work on Windows
I've just installed sage on windows. I downloaded the sage 5.1 disk and installed it under VirtualBox. Now when I attempted the tutorial trying to solve
x = var('x')
I got the following error:
You must install the optional Kash package to use Kash from Sage.
SInce I don't have access to the command line I couldn't attempt the solution described here.
In case this question has been asked before, i couldn't find it after searching.
What did I do wrong? How can I solve this? Thanks.
