Error when install numba by pip

I have the following error when trying to install by pip install numba on Ubuntu 16.04. Could you show me how to fix it.

I have tried this to solve this issue. $pip install wheel (or pip3 install wheel)

This made some more progress. But the final solution I found was below. $sudo apt install python3-numba

@Aldurine thank you for submitting this. I can see from the log that you are trying to install Numba on Python 3.9 – however, this Python version is currently not supported. Please try to use 3.6/3.7/3.8. Thank you for using Numba.
