我的本地Rails环境有什么问题？

Question

我在一年前开始使用Rails应用程序.这是一个Rails 2.3应用程序.

现在,其他人做了远程更改(它在Github上,对不起,但它是私有的).我做到了

sudo gem update

也就是说,更新了我的所有宝石,包括Rails(至3).

意识到这一点,我已经做到了

rake:freeze:edge RELEASE=2.3.8

或任何使这个版本使用该版本的rails,希望这是解决方案.

然而,到目前为止没有这样的运气.

尝试启动服务器时出错,并试图运行script/console(虽然它更成功).

请注意,这个确切的应用程序在EngineYard上运行正常.

服务器:

安慰:

在控制台中,我尝试使用已定义的模型:

我刚刚遇到这个错误,问题结果是我在database.yml文件中使用了tab而不是double-space.以为我会提到它,以防其他人遇到同样的麻烦.
