Python

Python 3.x is required to run two of the frameworks (ccm & pyactr).

1. Is it already installed?

You can check if you have it installed by opening a terminal (command-line interface) and trying to run it:

$ python --version
Python 3.10.4

On macOS, if you get a response like Python 2.7.16, try it with:

$ python3 --version
Python 3.10.4

If it is not installed, we need to install it.

You can either install it using the official installer from python.org or using homebrew if you use that:

brew install python3

This is going to depend on you flavour of Linux, but generally it will be something like:

$ sudo apt-get install python3.10 python3-pip python3-venv

The key is ensuring that python, pip, and virtual environments are available.

Installing it using the official installer from python.org is recommended.

To make gactar setup easier, ensure that you check the Add Python 3.10 to PATH checkbox when installing.

Open a new terminal and try repeating step 1 to see if everything was installed properly and the paths are correct.

If these instructions aren't enough to get you started, please take a look at one of the more in-depth install instructions available, or search on the internet.
