2 个解决方案

#1

Looks like you are running on Ruby 1.8.7, but the code you have written is only valid in Ruby 1.9.

看起来您在Ruby 1.8.7上运行，但是您所编写的代码在Ruby 1.9中是有效的。

If possible, I would recommend upgrading up to 1.9.3; that should fix the issue.

如果可能的话，我建议升级到1.9.3;这应该能解决这个问题。

If you cannot use Ruby 1.9.3, just change the line from

如果您不能使用Ruby 1.9.3，只需更改代码行

key: '_blog_session'

来

:key=>'_blog_session'

#2

Are you running Ruby 1.9.x? The error is on a line using the new 1.9 hash syntax which is not backwards compatible. Try running ruby --v and seeing what version you're running. If its a 1.8.x you'll need to upgrade Ruby in order to run the latest version of Rails.

你在运行Ruby 1.9.x吗?错误出现在使用新的1.9哈希语法的行上，该语法不向后兼容。尝试运行ruby -v，看看您正在运行的版本。如果它的1.8。为了运行最新版本的Rails，您需要升级Ruby。
