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，其他人进行了远程更改（它在Github上，抱歉，但它是私有的）。而且我已经完成了

sudo gem update

即更新了我的所有宝石，包括Rails（至3）。

意识到这一点，我已经完成了

rake:freeze:edge RELEASE=2.3.8

或任何使此版本使用该版本的rails，希望这是解决方案。

然而，到目前为止还没有这样的运气。

尝试启动服务器时遇到错误，并尝试运行script/console（尽管更多成功）。

请注意这个确切的应用程序在EngineYard上运行正常。

在控制台中，我尝试使用已定义的模型：

Answer 1

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。我以为我会提到它，以防其他人遇到同样的麻烦。

Answer 2

我的database.yml有一个迷路end个关键字。清理该文件解决了我的问题。感谢加勒特指出我正确的方向！

我的本地Rails环境有什么问题？
