@Steve-Mcl as i read topic as your recomended Difficulty to install node-red-contrib-xml-validate/xml-validate but still have issue import(function mode) [libxml-xsd] let you advise?
The error states: "can't find Python executable" was this installed ?
I believe @bakman2 is asking you if python is installed on the device running Node-RED.
Yes already installed python but still error same
