please suggest do?

/system/library/frameworks/ruby.framework/versions/2.0/... system library in os x yosemite.

ruby 2.2 (or other version) installed or other user -- perhaps via rvm, given have rvm gem installed? if need use rvm change default. if did not install rvm correctly or ignored warning or command gave you, might want re-install.

if did not install ruby 2.2 via rvm*, here instructions changing os x default ruby installed using brew.

(*i not recommend rvm more strongly. other people rbenv same job.)
