Install httpx without pulling anyio, trio and socks

[tbarbugli]

I have these dependencies installed with Poetry

[tool.poetry.dependencies]
python = ">=3.8.1,<4.0.0"
httpx = "^0.27.0"

This adds additional dependencies such as anyio, trio and socks that I am not using in the project. Unfortunately these dependencies come from httpx's httpcore dependency.

Is there a way to only get httpcore with no additional async libs?

httpx doesn't pull in trio or socks by default. (Perhaps take a closer look into why these are being included in your Python environment?)

It does currently pull in anyio and sniffio by default, and we're working on removing this. #2858
