Answer 1

as the name says, ring seems to have returned a 101 return message, meaning something is either missing or wrong in your setup. I don't have a mac so i don't know what dependencies does rust need, but at least make sure you have rustup properly installed. if you're sure that rustup is installed right, then you should use this method to solve it
