Can I use Requests library in a Python Worker

Ok, I don't remember where I read it, but I thought I could use the Requests library to do GET and POST requests. But, I'm getting ModuleNotFoundError: No module named 'requests' error.

No. You can use something like aiohttp or httpx

Here it mentions requests: 2.31.0 https://developers.cloudflare.com/workers/languages/python/packages/ Does that not mean that it can support it, or am I doing a very obviously dumb thing...

Cloudflare Docs

Python packages supported in Cloudflare Workers · Cloudflare Worker...

You can currently only use built-in packages in local development. Support for deploying packages with a requirements.txt file is coming soon.

So, this error occurs when I put requests in requirements.txt. Doesn't matter if I import requests or not. Ok... No matter whatever package I put in requirements.txt it still gives me that. This is the code in index.py

from js import Response

def on_fetch(request):
    print("Hi there!")
    return Response.new("Hello World!")

from js import Response

def on_fetch(request):
    print("Hi there!")
    return Response.new("Hello World!")

And this is what's in requirements.txt

httpx

httpx

And this is the Error
