Trouble installing Hoobs on Mac mini
I have an old mac mini with High Sierra. I was able to get the old Xcode (10.1) from the developer site. Got it installed and then installed Node.JS LTS. And then installed Hoobs. But I can't seem to get Hoobs to run. I tried the following at the command line: hoobs -p 'my user pwd' with that obviously being the user's pwd that I'm logged into on the mac (admin). I also edited sudoers so I wouldn't need a pwd using sudo visudo and adding NOPASSWD: to the %admin line. I then try just hoobs at the command line. I get the following error:
Calvin:~ calvin$ hoobs
Error: listen EACCES: permission denied 0.0.0.0:80

  port: 80
}
[HOOBS] Stopping server.

It seems to be installed but there seems to be some configuration messed up somewhere. Anybody have any idea? Any help is greatly appreciated. I am just comfortable enough with coding but i am no expert. As in I need explicit command line help. 
Thanks.
