Capistrano部署錯誤無法激活jruby-openssl-0.9.5-java

Question

我在JRuby（1.7.10）中開發了一個新的Rails（4.1.4）應用程序，我試圖在Capistrano v3上部署它遠程vps。錯誤我得到的樣子：

end 

看來錯誤的根源是雷神寶石。如果我刪除共享目錄中的bundle文件夾，那麼它會安裝所有的gem。但下一次失敗。使用'remove_shared_bundle'任務時，我試圖在每個部署工作之前刪除捆綁文件夾。但是，每次都需要重新安裝，這是需要時間的。

對此問題有補救措施嗎？

我認爲這個問題可能與JRuby的默認寶石在1.7.10 中不可更改有關，它已經被修復，所以最近的事情是嘗試JRuby 1.7.15（或至少1.7.13）

我會比的Gemfile不會宣佈gem 'jruby-openssl', '0.9.5'（完全刪除）讓JRuby中使用任何有可用 - 不知道是否有任何寶石拉時，也可以幫助（如果沒有寶石拉入捆綁作爲依賴）在1.7.10下解決它。
