| = Maintenance = The packages necessary to run sage are developed on the github pages of conda-forge. The actual [[https://github.com/conda-forge/sage-feedstock/tree/master/recipe|sage package]] and many of its dependencies are maintained by Isuru Fernando (and a few volunteers). |
The above instructions are being added to the Sage documentation in https://trac.sagemath.org/ticket/33655 |

Conda packages for Linux & macOS are available through conda-forge.
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
- i.e., open a Terminal,
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
The above instructions are being added to the Sage documentation in https://trac.sagemath.org/ticket/33655
Conda for Sage Developers
You can develop Sage without building any of its dependencies (experimental) --- on my machine this takes 5 minutes. Assume you obtained Sage source tree and changed to its root. These instructions have been updated for #30845 and are being added to the Sage installation guide in #33426
$ export SAGE_NUM_THREADS=24 # or whatever the meaningful value
# for your machine is - no more than
# the number of cores.
$ conda install mamba # This is a recommended optional step.
# If you skip it, replace "mamba" by
# "conda" in the following steps.
$ mamba create -n sage-build python=3.9 \
gettext autoconf automake libtool pkg-config # or replace 3.9 by another version
$ conda activate sage-build
$ ./bootstrap # this generates src/environment.yml
# used in the next step
$ mamba env update -n sage-build -f src/environment.yml # alternatively, use
# src/environment-optional.yml
# for some additional packages
$ conda activate sage-build
$ ./configure --with-python=$CONDA_PREFIX/bin/python \
--prefix=$CONDA_PREFIX \
$(for pkg in $(./sage -package list :standard: \
--has-file spkg-configure.m4 \
--has-file distros/conda.txt); do \
echo --with-system-$pkg=force; \
done)
$ pip install --no-build-isolation -v -v --editable pkgs/sage-conf pkgs/sage-setup
$ pip install --no-build-isolation -v -v --editable src
$ sage -c 'print(version())'
SageMath version 9.6.beta5, Release Date: 2022-03-12By using pip install --editable, the Sage library is installed in editable mode. This means that when you only edit Python files, there is no need to rebuild the library; it suffices to restart Sage.
After editing any Cython files, rebuild by repeating the command
$ pip install --no-build-isolation -v -v --editable src
