最近我将我的rails版本更新为4.2.3，将ruby版本更新为ruby-2.2.3。之后，当我捆绑它时会出现以下错误：
$ 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
你能帮帮我吗？
