TypeError: unsupported operand type(s) for |: 'type' and 'NoneType' in rpm_controller.py

I'm trying to test the examples of crewai, but the initial import of crewai fails.

I'm using crewai-0.5.0 langchain-0.1.0 langchain-openai-0.0.2.post1 on Python 3.9 on MacOS in a virtual environment.

Here's the code sample

import os
import dotenv
dotenv.load_dotenv() # defines environment variable OPENAI_API_KEY.

import crewai

This is the full stack trace:

The issue is with the python version, | was added in python 3.10, so not available in python 3.9 :)

get the same error here, so why not to use union type to fix this?
