Error: address already in use

[ryanwesslen]

hi @bulldog903!

Thanks for your post and welcome to the Prodigy community

I suspect you have an old session still running. After each time you run Prodigy e.g., python -m prodigy ... you need stop it when you're done by pressing CTRL + C.

What I think you're doing is trying to run a second process on the same 8080 port (hence "address already in use").

Prodigy bind error

Hi! This error usually means that there's already something else running on that port (8082). Maybe just try and check what it is, and kill it if it's a process you don't want? See here for examples: macos - Find (and kill) process locking port 3000 on Mac - Stack Overflow

What do you see when you run:

sudo lsof -i :8080

If see something running, find the pid and then run:

kill -9 <PID>

This will kill that session and hopefully you can run a new session.

Then the link http://localhost:8888 opens to the old file I was annotating.

Also, did you mean you tried to open http://localhost:8080, not http://localhost:8888? By default, when you run a Prodigy process, it'll serve it on the 8080 port so you'd need to view http://localhost:8080. Make sure you're looking at the correct port in your local browser as this could be a problem too.

Hope this helps!
