Ruby on rails Rails使用multi_json创建新问题

我不太确定创建新rails应用程序时最初的问题是什么，但似乎每次创建应用程序时，我都会遇到json问题。当我尝试执行gem安装

multi_json-v'1.8.1'

时，我也会收到一个错误。由于rubygems.org的服务器问题，gem似乎无法更新。我错过什么了吗

一个简单的

rvm osx ssl证书更新所有
将更新过时的证书。
您在mac上吗？您是否使用RVM管理您的红宝石？您遇到的错误是一个SSL错误，当您的ca_证书过期时会发生。您使用的是哪个版本的ruby？嘿，Leo，是的，我在mac上使用RVM。我在
ruby 2.0.0p247上。我可以在我的终端中运行这个来更新它吗：
rvm osx ssl certs update all
Yes这就是答案。
