[BUG] uvloop ModuleNotFoundError: No module named 'uvloop' on Ubuntu Docker Image

[Mikcl]

Description

Running a boilerplate robyn project within an ubuntu docker image on mac m1 fails due to missing uvloop runtime dependency. Able to build the image but an error occurs at runtime.

uvloop is a conditional dependency which does not get installated in this environment.

Expected Behavior

I would expect that, if uvloop is required in my environment that it is installed via pip install robyn. This seems like a bug in the conditional install logic?

I just verified this bug. And I was unable to replicate on x86_64 Linux and WSL.

I will try tomorrow with a docker on my arm mac.
