Just installed phantomjs, mac os x yosemite. Whenever I run /bin/phantomjs, with any parameter, I get Killed: 9. Any idea?
Whatever is in /usr/local/bin/phantomjs has stopped working for you.
If you've got ~30mins to spare you can reinstall and relink using brew:
# unlink old version
brew unlink phantomjs
# reinstall phantomjs
brew update && brew install phantomjs
# (You may wish to make a refreshing herbal tea or similar beverage here...)
# Update link to usr/local/bin
brew link --overwrite phantomjs
If you want to test what brew will do with overwrite you can run
brew link --overwrite --dry-run phantomjs
