Issue with importing SimpleDirectoryReader and other Similar Modules from llama_index.core: TypeError in Python 3.10

[crman]

Issue Description:
I am encountering an issue with importing modules like SimpleDirectoryReader from llama_index.core in Python 3.10. Previously, this functionality worked correctly, but now I'm receiving the following error message:

TypeError: Plain typing.TypeAlias is not valid as type argument.

I am using llama-index version 0.10.37.

I have reviewed the project's documentation and attempted common troubleshooting steps without success. Any guidance or suggestions on how to resolve this issue would be greatly appreciated!

The error message TypeError: Plain typing.TypeAlias is not valid as type argument suggests an issue with the typing module in Python 3.10. This can often be resolved by updating the typing-extensions package.

Try updating typing-extensions:

pip install --upgrade typing-extensions

If the issue persists, create a fresh virtual environment and reinstall the necessary packages:

# Create a new virtual environment
python -m venv llama_index_env

# Activate the virtual environment
# On Windows
llama_index_env\Scripts\activate
# On Unix or MacOS
source llama_index_env/bin/activate

# Install the required packages
pip install llama_index==0.10.37
pip install typing-extensions

This should help resolve the TypeError related to typing.TypeAlias ^[1].

having the same issue here, isn't this a major bug, surprised can't find many people asking about this issue

Exactly @ZhengRui! Ideally it should work with Python 3.10 but it is not working.
But what I found that it is working with Python version 3.11 and 3.12. I don't know what is the exact issue.
You also try changing the Python version, it should work.

Thanks for the suggestion, I will try out @crman
