Issue with Treehouse VM - Address already in use

I installed Ruby on my Mac and it worked fine. But then I installed Treehouse VM on my mac, and now when I enter bin/rails server in the terminal, I get the following in my terminal:

=> Booting WEBrick => Rails 4.1.4 application starting in development on http://0.0.0.0:3000 => Run rails server -h for more startup options => Notice: server is listening on all interfaces (0.0.0.0).

Is there a way to fix this or change the port? I think the Treehouse VM may be using the same port.

Thanks

Did you try turning off your Treehouse VM?
