``Hey, i'm not able to run chainlit on my computer.

I just grab the demo code:

import chainlit as cl

@cl.on_message  # this function will be called every time a user inputs a message in the UI
def main(message: str):
    # this is an intermediate step
    cl.Message(author="Tool 1", content=f"Response from tool1", indent=1).send()

    # send back the final answer
    cl.Message(content=f"This is the final answer").send()

And run:

❯ chainlit run demo.py -w

AttributeError: module 'select' has no attribute 'epoll'. Did you mean: 'poll'?

I'm missing something here?

Hello, someone had a similar issue and fixed it by setting a new env (https://discord.com/channels/1088038867602526210/1113461363197608047/1114256583317270600).

What python version os and terminal do you use?
