PhantomJS: getting “Killed: 9” for anything I'm trying

Question

Just installed phantomjs, mac os x yosemite. Whenever I run /bin/phantomjs, with any parameter, I get Killed: 9. Any idea?

Answer 1

Sometimes this happens when your current shell process is killed.

I was in tmux using brew update, and brew updated tmux and bash, then bang! Everything in tmux just returns Killed: 9.
