Setting Up

In short: Install sage from conda-forge.

To install sage on your machine (without the need for root permissions):

Install Miniforge3
export your PATH (and hash -r or rehash)
Make sure your locale is UTF-8.
Use conda-forge packages: conda config --add channels conda-forge; conda config --set channel_priority strict
create an environment for sage: conda create -n sage sage
enter your environment: source activate sage
enjoy: 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

There are still some issues with Conda. Not all tests pass and some things don't work:

#20382
…

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.
