Conda packages for Linux & macOS are available through conda-forge.

Setting Up

In short: Install sage from conda-forge.

• Download the latest release of Mambaforge, take the x86_64 one since not everything is packaged for ARM yet

• Install Mambaforge, i.e., open a Terminal, cd Downloads and sh Mambaforge-MacOSX-x86_64.sh

• Create a "sage" environment and pick a version of SageMath, i.e., open a new terminal and mamba create -n sage sage=9.2

• 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

Open Issues

General

To check whether there are known issues with Conda:

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.
