jupyter_ai fails to load on fresh Jupyter Lab installation in fresh Python 3.11 virtual environment #1497
Description
Description
jupyter_ai fails to load on fresh Jupyter Lab installation in fresh virtual environment using Python 3.11 on MacOS. This may also fail on other environments, but I have only tested on MacOS.
On fresh install, I see the following warning in jupyter lab console output on startup:

Thank you for your help with this issue!
Reproduce
On an Apple computer running MacOS, navigate to a fresh directory and run the following commands:
brew install python3.11 # Ensure running on python3.11
python3.11 -m venv .venv # Create a new virtual environment
. .venv/bin/activate # Activate the virtual environment
which pip # Confirm running the pip in venv
pip install jupyterlab # Install jupyterlab
pip install jupyter_ai # Install jupyter_ai extension
jupyter lab # Start jupyter lab
Note the following warning in startup:
