I installed SageMath version 8.3.beta5 on Linux Manjaro 2 days ago first time using its package manager (it build sage, took loooong time).
But for some reason, I can't use the ? help. As in sin? or anything. It gives an error
ImportError: No module named sphinx.application
For example
sage: sin?

sage:
I tried sin? on https://sagecell.sagemath.org/ and it works there. So I guess something is wrong with my setup or may be because I am using beta version?
But this was what got installed automatically for me when I searched package manager for sage.
thanks
