• ubuntu系统升级

  sudo apt update
  sudo apt upgrade
  sudo do-release-upgrade

pip install -i https://mirrors.ustc.edu.cn/pypi/web/simple pip -U pip config set global.index-url https://mirrors.ustc.edu.cn/pypi/web/simple

apt install python3.10-venv
python3 -m venv nano_project
source nano_project/bin/activate (activate路径)

• 生成项目requirement.txt

opencv 建议单独 sudo apt install python3-opencv
pip install pipreqs
对应目录下生成
pipreqs ./ --encoding=utf8
覆盖原requirement.txt
pipreqs ./ --encoding=utf8 --force

• 使用requirement.txt

pip install -r requirements.txt

sudo apt-get install libopencv-dev..

sudo apt-get install python3-dev
sudo git clone https://github.com/friendlyarm/RPi.GPIO_NP

• 生成whl文件方便使用(GPIO文件夹内已有whl文件)

cd RPi.GPIO_NP
pip install wheel
pip install build
python3 -m build --wheel -n -x
cd dist
保存whl文件

• 使用whl文件安装

cd GPIO 对应路径
pip install RPi.GPIO-0.5.8-cp38-cp38-linux_armv7l.whl
