Deply python and install dependencies within Node-RED-addon in Homeassistant
Frenck, the maintainer of node-red-addon declared,
Python is not needed to run node-red.
https://github.com/hassio-addons/addon-node-red/issues/1450#issuecomment-1260433209
So Python is not built in the node-red addon.
Athough it support the options of system_packages, npm_packages, and init_commands to extend its function. While a explicit method to implement Python script is still needed.
Nevigate to node-red-addon contianer from Terminal in HA
docker exec -it addon_<your addon id>_nodered /bin/bash
Choose a comfortable source of Alpine Linux (skip if it’s not needed)
sed -i 's/dl-cdn.alpinelinux.org/mirrors.tuna.tsinghua.edu.cn/g' /etc/apk/repositories
Add python and pip
apk add py3-pip
Choose a comfortable source of PyPI (skip if it’s not needed)
pip3 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple/
Install necessary Python packages
pip3 install requests beautifulsoup4
Implement the above in a flow
