How to get Helix to use a python virtual environment?

[clue44]

When opening a python file, Helix marks the python imports with a red dot and says "[import-error] Unable to import 'requests'" for example.

It does this no matter if the virtual python environment is activated or not before opening Helix with the python file.

How do I get Helix to use a virtual environment in the same folder as the python code?

Helix just runs the language server as is. You need to configure the LSP (pylsp?) to pick up the env

What I do is:

1. Install pylsp (and black) within the virtual environment.
2. Open a terminal and launch the virtual environment (source myvenv/bin/activate or venv\Scripts\Activate.ps1).
3. Launch helix from that terminal session.

Helix just launches pylsp without any specified path, so when the virtual environment is activated it will launch the pylsp from that environment (similar to directly running pylsp in the terminal after the environment is activated).
