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 don't think I should run make, since I downloaded a binary version, but I tried anyway and got a similar error:

RecursionError: maximum recursion depth exceeded during compilation
Makefile:31: recipe for target 'base-toolchain' failed
make: *** [base-toolchain] Error 1

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?

Alternatively, is there another possible source for this error?

My guess is that in the build process, there is something that ends up in an infinite recursion. Would there perhaps be a symbolic link somewhere in your system that creates a loop? If the build process does a filesystem tree search somewhere, then such a loop would likely cause an infinite recursion. Looking at the traceback of the cause of the RecursionError would probably provide you with a hint. Do you have more detailed error messages available?

@nbruin I put all the error messages that I saw. Where can I find more detailed messages?

Judging from where the error message you quote is raised, I suspect the error arises in sage-location. However, as https://ask.sagemath.org/question/351... indicates, it might not be necessary to trace the precise source of the error.

Please try with Sage 8.5 and report if you get the same error.

Run the following in a terminal and check what output you get:

python --version

This is a known issue that was resolved in Sage 8.5: https://trac.sagemath.org/ticket/25668 Another workaround is to install python2 and ensure that PYTHON=python2.
