Trying to start my rabbitmq server, but I get this error. I've followed all of the instructions on how to install it. The rabbitmq-server file lives inside /usr/local/sbin. So I change directory to sbin, and write rabbitmq-server in my terminal but it shows the error -bash: rabbitmq-server: command not found. I've already added the following line: export PATH=/usr/local/sbin:$PATH at the bottom of my bash_profile, as per instructions. Any idea why it isn't working?
