SageMath fully supports all major Linux distributions, recent versions of macOS, and Windows (Windows Subsystem for Linux).
The traditional and recommended way to install SageMath is from source via Sage-the-distribution (https://www.sagemath.org/download-source.html). Sage-the-distribution first builds a large number of open source packages from source (unless it finds suitable versions installed in the system) and then installs the Sage Library (sagelib, implemented in Python and Cython).
About this experimental pip-installable source distribution
This pip-installable source distribution sagemath-standard
is an experimental distribution of the Sage Library. Use at your own risk.
Building sagemath-standard
has a large number of system packages as prerequisites.
See https://doc.sagemath.org/html/en/installation/source.html#linux-recommended-installation
for partial lists for various systems.
The connection to the system environment is facilitated through the https://pypi.org/project/sage-conf/ distribution package.
A modularization effort is in progress with the goal of making it possible to install parts of the Sage Library with fewer prerequisites. https://github.com/sagemath/sage/issues/29705
