ruby-on-rails - 带有 Activesupport 3.2.0 的“Rails”

Question

我是 Ruby on Rails 的新用户，我现在尝试创建自己的博客来实践这个漂亮的框架。所以，在我执行此命令启动服务器后，我收到了这个错误，我认为是来自 ActiveSupport。我需要帮助:)

这是我收到的消息错误:

 ~/Bureau/blog$ rails server

看起来你在 Ruby 1.8.7 上运行，但你编写的代码仅在 Ruby 1.9 中有效。

如果可能，我建议升级到 1.9.3；那应该可以解决问题。

如果您不能使用 Ruby 1.9.3，只需更改以下行

key: '_blog_session'

到

:key=>'_blog_session'
