Hello. I am a university student in Japan, currently doing an internship using Universal Robots. I have a question because I encountered an issue. I downloaded SDK-polyscopex-0.14.74, opened VS Code from Ubuntu, and completed the setup. However, when I tried to run package.json, it didn’t work. I searched for the cause on other sites and tried to download npm, but that didn’t work either. Could you tell me which version is being used in package.json and what might be causing it not to work? My final task goal is to display the speed on the URcaps screen and check the route of the x, y, z coordinates using TCP. I am worried that I might not be able to complete the task within the internship period, so please help me. Thank you.
