Gem安装rails抛出UnknownHostError

Question

我正在尝试使用最新的mac OS让我的rails环境在Mac上工作。我安装了红宝石......

ruby -v
ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-darwin14.0]

当我尝试启动rails服务器时，我收到此消息......

rails -s
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.

所以我运行＆＃39; sudo gem install rails＆＃39;得到....

ERROR:  While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
    no such name (https://api.rubygems.org/gems/thread_safe-0.3.4.gem)

我如何解决此错误？
