it throwing error
It would be good to see this error
I could solve most of the Library issues in RED by right-click on the Library import statement within the .robot file and then “quick fix…”.
This adds the library path and the error has gone - try that.
Btw, my advise/personal opinion is to use the ImageHorizon Library for this.
The SikuliLibrary starts a Java-based Library server which has to translate the API calls.
ImageHorizon has a much smaller footprint because it directly uses the pyautogui Python module. Did several projects with it and never had problems.
