I get same issues like this , please fix. I'm using MAC OS

[mattn]

refresh_line is implemented on ruby19. you still using ruby19?

[haikieu]

I'm tried to install the readling from terminal by command: sudo port install readline but still get back the issue.

@mattn how to check & install ruby19 ?

I got working on mavericks using ruby 2.0.0 after following steps https://github.com/jugyo/earthquake/issues/169 by adding the 2 lines to the top of /bin/earthquake and commenting out line 30 of gems/twitter-stream-0.1.16/lib/twitter/json_stream.rb hope this helps
