I am developing a static site locally. To view it in a browser, I run this command
ruby -run -ehttpd . -p8000
to run a local webserver at localhost:8000.
Starting yesterday, when I run it, I get the error
INFO WEBrick 1.3.1
INFO ruby 2.0.0 (2015-12-16) [universal.x86_64-darwin16]
WARN TCPServer Error: Address already in use - bind(2)
INFO WEBrick::HTTPServer#start: pid=1158 port=8000
So I change the port number -p8000 to p8001 and I get the same error. I try 8002, 8003, 8888, 1313, 8004. I the same error on every single port number. Ruby, or Webrick, thinks that every port is already in use.
All the solutions to this problem I can find online suggest finding whatever process is hogging the port using commands like lsof | grep '8000' or lsof -wni tcp:8000 and then killing that process. But those commands don't return anything. There are no processes using those ports.
This happens on a fresh restart of my machine. Wifi turned off.
