Some LSPs (e.g. jedi-language-server) only find 3rd party sources if they are present in the python venv created by mason

[liviu-liviu]

Hi,

I've installed the jedi-language-server via mason. It works well when I search for definitions located inside the project but fails to find definitions in 3rd party source code (e.g. PyTorch).

I'm thinking this happens because mason has installed the LSP under a virtual environment and only finds packages that exist there. ~/.local/share/nvim/mason/packages/jedi-language-server/venv

It seems strange to need to install all my project dependencies a second time under this venv. But if I do, the LSP starts finding the missing definitions.

Is there a way to avoid having two sets of the same dependencies installed, one for my project and the other for the LSP venv?

The jedi-language-server should automatically "detect" the virtual environment. For this to work, I presume you'll have to activate the virtual environment either before launching Neovim, or somehow do it inside Neovim.
