2020-11-19 14:23:21 +0200 commented answer Unknown installation error in Windows

The problem was with the antivirus as suggested by Iguannaut. Now it works, but I had to uninstall the antivirus, and I would like to know how to have both...

I tried with 8.9 version of Sagemath and the problem persists. So it seems it has nothing to do with Python 3.

I installed the version 8.9 and same problem happens. So it seems the problem is not related to Python 3. Of coruse I tried to execute: sage -c "print(2+2)", but the answer was


Unhandled SIGSEGV: A segmentation fault occurred. This probably occurred because a compiled module has a bug in it and is not properly wrapped with sig_on(), sig_off().

Python will now terminate.

If I execute just "sage" in the shell, it starts sage but it stops after some seconds without any explanation. The same if I execute sage or sage notebook icons.

I installed Sagemath 9.1 from the executable. Almost nothing works: when I execute from desktop icon it just crashes, if I do from icon that says Notebook it crashes after saying

"Use Control-C to stop ...."

If I execute the shell, I can use without problem "sage -python", "sage -gap", etc, but if I execute

sage -c

then it says


Unhandled SIGSEGV: A segmentation fault occurred. This probably occurred because a compiled module has a bug in it and is not properly wrapped with sig_on(), sig_off().

/opt/sagemath-9.1/src/bin/sage-python line 2: 1615 Segmentation fault (overflow memory)sage -python "$@"

Do you have any suggestions about how to solve the problem? I reinstalled Sagemath several times, but everytime there is the same problem.
