Conda packages for Linux & macOS are available through conda-forge.
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: 2022-03-12
By 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
