问题
Recently I have update my rails version to 4.2.3 and ruby version to ruby-2.2.3. After that when I do bundle it gives following error:
$ bundle
Fetching gem metadata from http://rubygems.org/..........
Fetching version metadata from http://rubygems.org/...
Fetching dependency metadata from http://rubygems.org/..
Could not find celluloid-0.16.1 in any of the sources
Could you help me?

Version 0.16.1 of the celluloid gem was yanked and is not available anymore. You will need to downgrade to 0.16.0 or upgrade to 0.17.x. Run:
bundle update celluloid
