Question

我有一个运行Ruby ruby 1.9.3p194和Capistrano 2.12.0的Rails 3.2.18应用程序。

我以前能够部署到我们的生产服务器，但我现在正尝试部署到不同的服务器（Ubuntu 12.04 LTS 64bit）进行测试。所以我用所有正确的信息（服务器ip，app name，repo等）改变了我的deploy.rb。

当我进行上限部署时，我得到以下内容：

  * executing `deploy:update'
 ** transaction: start
  * executing `deploy:update_code'

看起来bcrypt-ruby无法安装。但是即使捆绑器安装在服务器上也无法运行（必须在部署之前手动完成）

任何人都知道为什么会发生这种情况？

Answer 1

我通过执行以下操作解决了这个问题。

安装ruby1.9.1-dev并手动安装bundler gem。

现在所有宝石都在我的服务器上正确构建。

Gem :: Installer :: ExtensionBuildError：错误：无法构建gem原生扩展。 Rails Capistrano
