Setup Errors - Can't install on Raspberry Pi 4

[JonLevin25]

I'm trying to install from pip3 on a Raspberry Pi 4 running RetroPi / Raspbian Buster.

Setup collects packages, and then fails on setup.py stating:

    ******************************************************************************
    * Setup can't determine the value of PAGE_SIZE on your system, so it will
    * default to 4096 which may not be correct.
    *
    * Please report this message and your operating system info to the package
    * maintainer listed in the README file.
    ******************************************************************************

More diagnostics/troubleshooting tried:

• I've managed to install the library previously on a Raspberry Pi 3 (Which I think was also running Buster)
• I've managed to install other python packages on the Pi 4 using pip3 install i.e. tornado, colorzero etc.
• I've run sudo apt update && sudo apt upgrade + rebooting- same issue
• I've tried python 2 (pip install pip install adafruit-circuitpython-neopixel) - same error

I'm not sure if this is a system configuration issue on my end or some hardware/OS incompatibility, but would really like to get Neopixels up and running on the Pi - any help would be appreciated

Thanks

paste the full output and command you are running with verbose output, because that error isnt coming from this library

Attaching Verbose output - The command was pip3 install --verbose adafruit-circuitpython-neopixel.
I also installed wheel in between to see if it would help, no dice so far.

Someone on StackOverflow suggested installing python3-dev. Not entirely sure why it was necessary, but it worked :)
