Summary: I was running RN 0.31 on ArchLinux (kernel 4.7), and "react-native start" was refusing to run on the default (and sometimes required, as I have noticed) port. I tried executing the suggested lsof command, but that did not work. Somewhere I found the lsof command I include in this commit, and that worked (it was a node.js process). So I'm including it, since I found it helpful.
