我在JRuby（1.7.10）中开发了一个新的Rails（4.1.4）应用程序，我试图在远程vps上使用Capistrano v3进行部署。我得到的错误看起来像：

似乎错误的根源是Thor宝石。如果我删除共享目录中的bundle文件夹，那么它会安装所有的gem。但它下次失败了。使用'remove_shared_bundle'任务，我尝试在每次部署之前删除捆绑文件夹。但是每次都会花时间进行全新安装。
这个问题是否有补救措施？
答案 0 :(得分：1)
我认为这个问题可能与JRuby的默认宝石在1.7.10中无法更改有关 ...它已经修复了，所以最重要的是尝试JRuby 1.7.15（或至少1.7.13）
我不会在 Gemfile中声明gem 'jruby-openssl', '0.9.5' （完全删除它）让JRuby使用它可用的任何东西 - 想知道是否有任何宝石将其拉入，这也可以帮助（如果没有宝石将它作为依赖项拉入捆绑中）在1.7.10下解决它。
