Still in BETA! Don't use mamba to install something in valuable environments!
Mamba is a reimplementation of the bits which are somewhat slow in conda. Mamba uses:
- parallel downloading of JSON files using multiprocessing, and reusing conda's caches
- libsolv for speedy dependency solving, a state of the art library used in the package manager of Fedora and others
At the same time, mamba re-uses a lot of conda's codebase to parse the command line and execute the transaction (installation & deinstallation of packages).
From conda-forge:
conda install mamba -c conda-forge
From Source:
Make sure to have the following requirements in your conda environment:
conda install pybind11 libsolv pip -c conda-forge
If you build mamba in a different environment than base, you must also install conda in that environment:
conda install conda -c conda-forge
For a local (dev) build, run pip install -e .. This will build and install mamba
in the conda environment.
Now you are ready to install packages with mamba install xtensor-r -c conda-forge for example.
