Pixi for Python virtual environment management in 2024

Okay. This looks good in 2024: https://pixi.sh I came to it after failing over and over with poetry. I thought I knew it. But I don’t for sure.

First stop long ago was pyenv, then virtualenv, then mamba, and maybe a couple other Python environment packages … then it was poetry, and now it's pixi. Hmmmm https://t.co/SmFk8SgqnA definitely has my attention.

On MacOS I did the following to run the crew agent framework flawlessly using Pixi.sh

% brew install pixi

On Windows you install it this way.

Then, to try it out I did a:

% pixi init crewai
% cd crewai
% pixi add python
% pixi add --pypi crewai
% pixi add --pypi crewai-tools

I then added their hello_world.py example and they have a nice abstraction around how to make it into a task:

% pixi task add hello python hello_world.py
% pixi run hello

Or you can run the python file directly:

% pixi run python hello_world.py

It’s also possible to init pixi within an existing directory by just doing

% pixi init
