Go to the solution about Ruby Gem can't connect to rubygems.org

Why is there this?

Due to domestic network reasons (you know), the intermittent connection to the resource file that rubygems.org stored on Amazon S3 failed. So you will encounter gem install rack or bundle install when the time is not responding, specifically can be used gem install rails -V to view the execution process.

This is a full rubygems.org image, you can use this instead of the official version, the synchronization frequency is currently15 minutes at a time to ensure that the official services are as synchronized as possible.
How to use?

$ gem Sources--remove https://rubygems.org/$ gem sources-a https://ruby.taobao.org/$ gem sources-l*** current S Ources ***https://ruby.taobao.org# Make sure only ruby.taobao.org$ gem Install rails   

If you are using bundles (Rails project)

' https://ruby.taobao.org/'rails '4.1.0'. .
