Install Python

Check whether Python is already installed

Aetherflux requires Python version 3.9 or greater, and it must be available on your system path. Open a terminal and run:

python --version

On macOS, you may need to use the following instead:

python3 --version

If the command prints a version at or above 3.9, you are ready to continue with installing Aetherflux.

Download the Python installer

If Python is missing, or your installed version is too old, you can download a current release from the official Python downloads page:

• Windows
• macOS

Any supported 3.9+ release will work. If you are unsure of which to pick, the latest stable Python 3 release is a safe choice.

Install Python and add it to your PATH

Run the installer for your platform and follow the on-screen steps.

On Windows, make sure you enable Add python.exe to PATH (or the equivalent option) before finishing the install. Without this, Aetherflux will not be able to find your Python runtime. If you already installed Python and skipped that step, re-run the installer, choose Modify, and enable the PATH option.

On macOS, the official python.org installer will place Python on your system in the usual location. After installation, open a new terminal window so your shell picks up the updated path.

Confirm the install

Close and reopen your terminal, then run one of the following again:

python --version

python3 --version

You should see a version of 3.9 or newer.

If you have multiple Python versions installed, that is fine. Like other IDEs, Aetherflux lets you select the runtime of your choice once the application is running.

Next steps

With Python in place, continue to install Aetherflux. If you also want local AI assistance inside Aetherflux, see install Ollama.
