openMotor creator here. It sounds like you are trying to run the software from source. I can help you figure out why the dependencies aren't installing, but I would need more details than that. Feel free to send me a PM if you don't want to post the output publicly (though that should only disclose your computer username). Alternatively, you can use a prebuild release if you are on Windows or Mac OS as Reinhard pointed out. If you are on Windows, I suggest the "unpacked" build as it starts significantly faster than the single file build.
ok well i figured it out i click on the latest release and found the download link at the bottom and it seems to work I think I first download the sourecode then idk what the heck I was doing with the terminal but it didn't work but I figured it out
