所以我对rails等很陌生，过去几个小时我一直在尝试安装它，并且在尝试运行时遇到以下错误rails s，或者如果我尝试安装它rails g forem:install

您收到的错误是由于您在不支持它的旧版本 Ruby 中使用 Ruby 1.9+ 哈希语法。您需要将 Ruby 升级到 1.9.2 或 1.9.3，或者将 session_store.rb 文件的第二行更改为：

# Be sure to restart your server when you modify this file.
Forums::Application.config.session_store :cookie_store, :key => '_forums_session'
