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

Question

我已經在JRuby（1.7.10）中開發了一個新的Rails（4.1.4）應用程序，並且嘗試將Capistrano v3部署在遠程vps上。 我得到的錯誤看起來像：

    end
  end
end

看來錯誤的根源是托爾寶石。 如果我刪除共享目錄中的bundle文件夾，那么它將安裝所有gem。 但是，下一次失敗。 通過“ remove_shared_bundle”任務，我嘗試在每次部署成功之前先刪除bundle文件夾。 但是，這將在每次耗時的情況下進行全新安裝。

這個問題有補救辦法嗎？

Answer 1

我認為此問題可能與JRuby的默認gem在1.7.10中不可更改有關……此問題已得到修復，因此直接的事情是嘗試JRuby 1.7.15（或至少1.7.13）。

我絕不會在Gemfile中聲明gem'jruby gem 'jruby-openssl', '0.9.5' （完全刪除），讓JRuby使用可用的任何東西-想知道是否有任何gem將其引入 ，這是否也有幫助（如果有的話）沒有寶石將其作為依賴項拉入捆綁包）在1.7.10下解決。
