Question

我是Ruby on rails的新用户，我现在尝试创建我的博客来练习这个漂亮的框架。因此，在我执行此命令以启动服务器后，我收到了此错误，我认为来自ActiveSupport。我需要帮助:)

这是我收到的消息错误：

 ~/Bureau/blog$ rails server

Answer 1

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。

如果可能的话，我建议升级到1.9.3;应该解决这个问题。

如果您不能使用Ruby 1.9.3，只需从

更改行

key: '_blog_session'

到

:key=>'_blog_session'

Answer 2

你在运行Ruby 1.9.x吗？错误是使用新的1.9哈希语法在一条线上，该语法不向后兼容。尝试运行ruby --v并查看您正在运行的版本。如果是1.8.x，则需要升级Ruby才能运行最新版本的Rails。

使用Activesupport 3.2.0进行“Rails”
