ruby on rails - Cannot load gem during gem pristine -

-

i using rails on local host , have been confronted following message.

warning: you're using rubygems 1.8.23 spring. upgrade @ least rubygems 2.1.0 , run `gem pristine --all` better startup performance.

sounds fair enough, when run suggested command, hangs on installing cairo gem following message.

cached gem cairo-1.12.8 not found, attempting fetch... error:  while executing gem ... (gem::exception)     cannot load gem @ [/usr/share/rubygems-integration/1.9.1/cache/cairo-1.12.8.gem] in     /home/me/

what might going on here?

you need update rubygems 2.1.0 or newer versions. newest version 2.4.5 updated dec. 3rd 2014. try link update. https://rubygems.org/gems/rubygems-update
