I am using rails on my local host and have recently been confronted with the following message.

Warning: You're using Rubygems 1.8.23 with Spring. Upgrade to at least Rubygems 2.1.0 and run `gem pristine --all` for better startup performance.

Sounds fair enough, however when I run the suggested command, it hangs on installing the cairo gem with the following message.

Cached gem for cairo-1.12.8 not found, attempting to fetch...
ERROR:  While executing gem ... (Gem::Exception)
    Cannot load gem at [/usr/share/rubygems-integration/1.9.1/cache/cairo-1.12.8.gem] in     /home/me/

What might be going on here?

  • did you upgrade your rubygems bu `sudo gem update system` – Rajarshi Das Dec 16 '14 at 11:14
  • @RajarshiDas Thanks for the reply! Got a "nothing to update" response and the error still persists. – neanderslob Dec 17 '14 at 22:11
  • I found this forum post when trying to solve another problem http://stackoverflow.com/a/23668399/2540204 From this, I ran `gem install rubygems-bundler` and `gem regenerate_binstubs` This got rid of the error `Warning: You're using Rubygems 1.8.23 with Spring. Upgrade to at least Rubygems 2.1.0 and run 'gem pristine --all' for better startup performance.` But when I run `gem pristine --all`, I still get the error regarding the cairo gem. – neanderslob Dec 17 '14 at 22:43

You need to update your rubygems to the 2.1.0 or newer versions. The newest version is currently 2.4.5 it was updated Dec. 3rd 2014. Try this link to update. https://rubygems.org/gems/rubygems-update

Hi all I ended up finding a post that recommended I just reinstall ruby again. Seeing no other choice I did a rvm uninstall ruby then a rvm install ruby and set everything else back up and it went well. Unsatisfying but true :-P
