我的本地Rails環境出了什么問題？

Question

我一年前開始有一個Rails應用程序。 這是一個Rails 2.3應用程序。

現在，其他人進行了遠程更改（抱歉，該更改在Github上，但是是私有的）。 我做了

sudo gem update

也就是說，將我所有的寶石，包括Rails（更新為3）更新了。

意識到這一點，我已經做到了

rake:freeze:edge RELEASE=2.3.8

或任何使該版本使用該版本的rails的方法，希望這是解決方案。

但是，到目前為止還沒有這樣的運氣。

我在嘗試啟動服務器並嘗試運行script/console遇到錯誤（盡管更成功）。

請注意， 此確切的應用程序在EngineYard上可以正常工作。

當我在控制台中嘗試使用定義的模型時：

@mm = MyModel.find（：all）NameError：來自/Users/ajh/Sites/PROJECT_NAME/vendor/rails/activesupport/lib/active_support/dependencies.rb:443:in load_missing_constant' from /Users/ajh/Sites/PROJECT_NAME/vendor/rails/activesupport/lib/active_support/dependencies.rb:80:in未初始化常量MyModel來自/Users/ajh/Sites/PROJECT_NAME/vendor/rails/activesupport/lib/active_support/dependencies.rb:92:in的load_missing_constant' from /Users/ajh/Sites/PROJECT_NAME/vendor/rails/activesupport/lib/active_support/dependencies.rb:80:in const_missing' （irb）中的const_missing：1

Answer 1

我只是遇到了這個錯誤，結果是我在數據庫.yml文件中使用了一個制表符而不是一個雙空格。 以為我會提到它，以防其他人遇到同樣的麻煩。

Answer 2

我的database.yml有一個流浪end關鍵字。 清理該文件解決了我的問題。 感謝Garrett為我指出正確的方向！
