Question

我刚刚开始使用Rails并且我第二次启动了我的服务器，但是我收到以下错误消息？我还没有修改/ config / initializers中的任何Ruby文件。

george@ubuntu:~/Desktop/blog$ rails 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

Answer 1

看起来你正在运行ruby 1.8版。您需要升级到1.9。

ruby 1.8不支持key: 'value'哈希语法（需要:key => 'value'）。

如果这不是一个选项，你可以手动更改所有这些哈希值，但要注意Rails对ruby 1.8的支持已经不多了。

Answer 2

尝试Blog :: Application.config.session_store：cookie_store，：key =＆gt; '_blog_session'

Rails服务器不会在配置/初始化器中启动语法错误
