Yes, it looks like the script does not check if nginx config is there before opening it. Adding --config option helps, but a more helpful error message would definitely be more friendly anyways.

This is because nginx is not available in your PATH, so ngxtop cannot check to find config file location. But yah, the error message is not so helpful in this case, I'll try to fix that.
