我刚刚开始使用 Rails，我已经第二次启动我的服务器，但我收到以下错误消息？我也没有修改 /config/initializers 中的任何 Ruby 文件。

george@ubuntu:~/Desktop/blog$ rails server
=> Booting WEBrick
=> Rails 3.2.8 application starting in development on `http://0.0.0.0:3000`
=> Call with -d to detach
=> Ctrl-C to shutdown server

    from /home/george/Desktop/blog/config.ru:1

config/initializers/session_store 的内容如下。

# Be sure to restart your server when you modify this file.

Blog::Application.config.session_store :cookie_store, key: '_blog_session'

# Use the database for sessions instead of the cookie-based default,
# which shouldn't be used to store highly confidential information
# (create the session table with "rails generate session_migration")
# Blog::Application.config.session_store :active_record_store

看起来您正在运行 ruby​​ 1.8 版。您需要升级到 1.9。

key: 'value'ruby 1.8 不支持哈希语法（它需要在哪里）:key => 'value'。

如果这不是一个选项，您可以手动更改所有这些哈希值，但请注意 Rails 对 ruby​​ 1.8 的支持即将耗尽。

试试 Blog::Application.config.session_store :cookie_store, :key => '_blog_session'
