的Rails 3.2，Heroku的棄用警告 - 「棄用警告：您的Rails 2.3式插件」

Question

可能重複：
Rails 2.3-style plugins and deprecation warnings running task in Heroku

前幾天，我決定升級我的Rails 3.1應用程序到Rails 3.2。無論是在生產環境還是在開發環境中，我的本地機器都能正常運行。當我將應用程序推送到Heroku時，出現錯誤，應用程序崩潰。

錯誤消息：

我通過電子郵件Heroku的支持和響應是

你好 -

最後一行指向霧問題 - 一個用於與雲提供商（如亞馬遜）通信的庫。

你會確保'霧'寶石已被添加到您的應用程序？

我100％肯定的寶石那裏，你可以看到我的寶石file.Then再次另一個響應

您能夠在「生產」模式重現本地這個問題？

如果添加了「薄」寶石到你的Gemfile中，你可以模擬Heroku的環境「捆綁高管薄開始-e生產」

我已經完成了這一切，並在我的本地機器上運行。我對解決方案有點失落。我讀了這個Rails 2.3-style plugins and deprecation warnings running task in Heroku，我不願意嘗試這種黑客解決方案。作爲另一個解決方案，我決定將我的應用降級到Rails 3.1，問題仍然存在。我在這裏錯過了什麼？

我懷疑這是來自Carrierwave寶石，我已經與上傳器一起移除。但Heroku仍然指它。我的配置文件中沒有關於載波的內容。

Answer 1

這個錯誤與我所看到的插件或Rails 3.2無關，它們是棄用的。它看起來像你已經錯誤地卸載了carrierwave。

錯誤消息指出您仍然有config/initializers/carrier_wave.rb，並且仍在嘗試引用丟失的CarrierWave對象。

我建議確保您的載波被正確刪除，並且也從git中刪除。
