Hello everyone,

I want to share a method that seems **undocumented** but works perfectly.

## The discovery

Inside `CondaPkg.jl` , when using the Pixi backend, you can directly call `pip` to install any PyPI package:

bash

/home/$USER/.julia/environments/v1.12/.CondaPkg/.pixi/envs/default/bin/python -m pip install pandas pyarrow

## Why it matters

- **Much faster** than Conda backend
- **Access to PyPI** packages, not just Conda-forge
- **Reproducible** environment (via `pixi.toml` + `pixi.lock` )
- **Isolated** per Julia project

## Minimal working example

1. Add `CondaPkg` to your project
2. Enable Pixi backend (automatic in latest versions)
3. Run the `pip` command above
4. Now `PythonCall` can `import pandas` !

## Questions to the community

- Is this officially supported or a hack?
- Could this be documented properly?

I searched the docs and found no mention of this. Has anyone else tried this?

Looking forward to your insights.

I have no idea if this is related but I think there is a `CondaPkg.add_pip(...)` functionality somewhere in the docs. Might be doing this under the hood?

It’s unrelated. I installed pip directly via the mentioned path.

However, there are two methods:

Method 1: Calling the `env` Python path will run Python, which is supported by the system.  
Method 2: The path mentioned is for Python; it’s unrelated to Python. I mentioned the path in Pixi.
