I have Ubuntu 16.04. I downloaded the binary file "sage-8.4-Ubuntu_16.04-x86_64.tar.bz2", extracted it with:
tar jxf sage-8.4-Ubuntu_16.04-x86_64.tar.bz2
then went into the folder and ran sage:
cd SageMath
./sage
I got the following error:
RecursionError: maximum recursion depth exceeded during compilation

It seems that you are attempting to run Sage from an unpacked source
tarball, but you have not compiled it yet (or maybe the build has not
finished). You should run `make` in the Sage root directory first.
If you did not intend to build Sage from source, you should download
a binary tarball instead. Read README.txt for more information.

I found some notes saying that it might be related to the Python version. I have both 3.7 and 2.7. Should I somehow tell SageMath to use 2.7? How?
