• Python 2.7, 3.6, or 3.7 (as of JAWS version 0.7)

Installing pre-built binaries with conda (Linux, Mac OSX, and Windows)

By far the simplest and recommended way to install JAWS is using conda (which is the wonderful package manager that comes with Anaconda or Miniconda distribution).

To avoid dependencies version mismatch, it is recommended to create a separate conda environment as following:

$ conda  create --name jaws_env python=3.7
$ source activate jaws_env

You can then install JAWS and all its dependencies with:

$ conda install -c conda-forge jaws

Installing from source

If you do not use conda, you can install JAWS from source with:

$ pip install jaws

(which will download the latest stable release from the PyPI repository and trigger the build process.)

pip defaults to installing Python packages to a system directory (such as /usr/local/lib/python2.7). This requires root access.

If you don’t have root/administrative access, you can install JAWS using:

$ pip install jaws --user

--user makes pip install packages in your home directory instead, which doesn’t require any special privileges.


Users should periodically update JAWS to the latest version using:

$ conda update -c conda-forge jaws


$ pip install jaws --upgrade
