Setting Up

In short: Install sage from conda-forge.

Download and install Mambaforge.
- i.e., open a Terminal,
  - curl -L -O https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-$(uname)-$(uname -m).sh
    sh Mambaforge-$(uname)-$(uname -m).sh
Create a "sage" environment and pick a version of SageMath, i.e., open a new terminal and mamba create -n sage sage=9.3
To run SageMath, activate the environment you just created and run SageMath, i.e., source activate sage and sage

Maintenance

The packages necessary to run sage are developed on the github pages of conda-forge. The actual sage package and many of its dependencies are maintained by Isuru Fernando (and a few volunteers).

Conda for Sage Developers

You can develop Sage without building any of its dependencies (experimental). On my machine this takes 5 minutes:

$ export SAGE_NUM_THREADS=24
$ conda install mamba
$ mamba create -n sage-build sage boost-cpp
$ conda activate sage-build
$ mamba uninstall --force sagelib
$ ./configure --prefix=$CONDA_PREFIX
$ cd src
$ python setup.py install
$ sage -c 'print(version())'
SageMath version 9.2, Release Date: 2020-10-24

Windows

There is likely not going to be a working package in the near future, see https://groups.google.com/d/msg/sage-devel/wyaV8x5qolI/jVS4DKBvCAAJ.
