【问题描述】：
我正在尝试在运行 Raspbian Buster / RetroPi 的 Raspberry Pi 4 上安装上述库。
安装程序收集包，然后在setup.py 上失败，说明：
* Setup can't determine the value of PAGE_SIZE on your system, so it will
* default to 4096 which may not be correct.
尝试了更多诊断/故障排除：
- 我之前在 Raspberry Pi 3 上安装了相同的软件包，没有问题（我认为它也在运行 Buster）
- 我已经成功地使用
pip3 install即tornado、colorzero等在 Pi 4 上安装了其他 python 包。 - 我已经运行
sudo apt update && sudo apt upgrade+ 重新启动 - 没有帮助 - 我试过 python 2 (
pip install pip install adafruit-circuitpython-neopixel) - 同样的错误
任何帮助将不胜感激 - 谢谢！
完全错误：
pip3 install adafruit-circuitpython-neopixel

【问题讨论】：
-
Mods - 我不确定这是否更适合 Rpi 站点，因为它主要是关于 Python 包，但它可能特定于 Rpi。如果您认为合适，请随意移动它。
-
完整的错误回溯？
-
对了，忘记贴了，抱歉。编辑帖子以包含它。
-
你试过
pip3 install wheel然后再尝试安装吗？ -
如果这不起作用，请尝试
sudo apt install python3-dev，然后再次尝试安装。
