Juicer on OSX El Capitan ~ wrong number of arguments (2 for 0) (ArgumentError)

[novalagung]

I've installed juicer on my osx el capitan (I use ruby which is installed from homebrew), and I got this error. Previously when I used maverick, there was no problem (I use the same version of juicer, 1.2.0).

novalagung:~ $ juicer
/usr/local/lib/ruby/gems/2.2.0/gems/cmdparse-3.0.1/lib/cmdparse.rb:796:in `initialize': wrong number of arguments (2 for 0) (ArgumentError)

    from /usr/local/bin/juicer:23:in `<main>'

Same here. My stacktrace:

Any resolution to this?
