Rails服务器即使捆绑安装后也退出

我正在尝试运行depot_a rails3.1.0示例，其中可以下载here的书“Agile Web Development with Rails 4th edition”。Rails服务器即使捆绑安装后也退出

即使在致电rails server之前运行bundle install，我也会收到各种错误，我无法解密。任何想法如何解决这个问题？

谢谢。

您使用的是Ruby 1.8.x吗？看来，您正在使用的1.9.x风格哈希符号，这1.8.x的无法破译而不是

hash = { a: 1, b: 2}

你应该使用：

hash = { :a => 1, :b => 2 }

的问题是在config/initializers/session_store.rb:11，如果您仍然卡住，请发布此行的代码。

很确定这本书的最新版本使用了新的风格：{） – Rasmus

如果您按照入门Rails和在Mac OS X Lion中，运行

rails server

希望帮助之前运行

rvm use --default 1.9.2

。
