Ruby on rails 在新的RubyonRails应用程序中有一些错误

当我想创建一个新的ruby on rails应用程序时，我在终端中键入“rails new depot”，它有如下错误消息：

"An error occurred while installing multi_json (1.5.1), and Bundler cannot continue.
Make sure that `gem install multi_json -v '1.5.1'` succeeds before bundling."

以下是完整的输出：

如何处理这个问题？

[Edit]经过一些研究，我意识到我的问题是没有最新的openssl证书。在较旧的Ruby环境中，它们很好，但在我的RVM 2.0+安装中，它们不是

要更新证书，请按照以下说明操作：
