Simple way to manage version, environments, and packages. https://conda.io/miniconda.html

Installation

Download and run the bash installer for your platform, listed below.

macOS

curl https://repo.continuum.io/miniconda/Miniconda3-latest-MacOSX-x86_64.sh -o Miniconda3-latest-MacOSX-x86_64.sh
bash Miniconda3-latest-MacOSX-x86_64.sh

At the end of setup, answer "yes" when it asks if you want to add miniconda to your PATH:

Do you wish the installer to prepend the Miniconda3 install location
to PATH in your /home/<user>/.bash_profile ? [yes|no]
[no] >>> yes

Appending source /home/<user>/miniconda3/bin/activate to /home/<user>/.bash_profile
A backup will be made to: /home/<user>/.bash_profile-miniconda3.bak

For this change to become active, you have to open a new terminal.
